(diff114a, diff114b, diff114c) * dbg_mlc.c: Guard include <errno.h> with ifndef MSWINCE; include "private/dbg_mlc.h" before it. * malloc.c: Ditto. * dbg_mlc.c (GC_debug_strdup): Use memcpy() instead of strcpy() for WinCE (since deprecated); evaluate strlen() only once; don't set errno for WinCE. * malloc.c (GC_strdup): Ditto. * dyn_load.c (GC_wnt): Define as macro (FALSE) for WinCE. * include/gc.h (GC_unregister_my_thread): Refine the comment. * include/gc.h (GC_uintptr_t, GC_beginthreadex, GC_endthreadex): Don't declare for WinCE. * include/gc.h (GC_WINMAIN_WINCE_LPTSTR): New macro (WinCE only). * include/gc.h (GC_WinMain): Remove GC_API. * include/gc.h (GC_WinMain): Use GC_WINMAIN_WINCE_LPTSTR for lpCmdLine. * tests/test.c (GC_WinMain): Ditto. * win32_threads.c (main_thread_args, GC_WinMain): Ditto. * include/gc_config_macros.h (ptrdiff_t): Guard with ifndef _PTRDIFF_T_DEFINED; define _PTRDIFF_T_DEFINED macro. * include/private/gc_locks.h: Guard include "atomic_ops.h" with ifdef GC_PTHREADS (and not GC_WIN32_THREADS). * mark.c: Include "atomic_ops.h" if PARALLEL_MARK. * thread_local_alloc.c: Include "atomic_ops.h" if GC_GCJ_SUPPORT. * win32_threads.c: Include "atomic_ops.h" if MPROTECT_VDB. * include/private/gc_locks.h: Use include "atomic_ops.h" instead of include <atomic_ops.h>. * include/private/gc_priv.h: Ditto. * include/private/gc_locks.h (GC_allocate_ml, GC_need_to_lock): Don't export (replace GC_API to "extern"). * win32_threads.c (GC_allocate_ml): Don't export. * include/private/gc_priv.h (DebugBreak): Define as macro for WinCE (if not UNDER_CE and DebugBreak is not defined yet). * include/private/gc_priv.h (UNALIGNED): Rename to UNALIGNED_PTRS (since "UNALIGNED" is defined in winnt.h of WinCE). * mark.c (UNALIGNED): Ditto. * include/private/gcconfig.h (ARM32): Recognize _M_ARM and _ARM_. * include/private/gcconfig.h (ALIGNMENT): Check always defined. * include/private/gcconfig.h: Allow GC_WIN32_THREADS for WinCE. * include/private/thread_local_alloc.h: Define USE_WIN32_SPECIFIC for WinCE (since __declspec(thread) is unsupported). * include/private/thread_local_alloc.h (TLS_OUT_OF_INDEXES): Define for WinCE (if undefined). * malloc.c (GC_malloc): Remove outdated comment about disabling signals. * misc.c: Don't include <tchar.h> (since not used anymore and may break TEXT() macro defined in winnt.h). * misc.c (GC_init_inner): Don't use GetModuleHandle() and InitializeCriticalSectionAndSpinCount() for WinCE. * misc.c (GC_init_inner): Replace GetModuleHandleA() with GetModuleHandle() (and use TEXT() macro controlled by UNICODE). * misc.c (LOG_FILE): Remove unused macro; don't use _T() macro. * misc.c (GC_CreateLogFile): New static function (Win32/WinCE only); move the code from GC_write(); replace GETENV() with GetEnvironmentVariable(); replace CreateFileA() with CreateFile(); use TEXT() macro (for Unicode support); replace strcat() with memcpy() (since deprecated in WinCE). * misc.c (GC_write): Define as STATIC. * win32_threads.c (GC_attached_thread): Ditto. * misc.c (GC_write): Use GC_CreateLogFile(). * misc.c: Define vsnprintf macro as StringCchVPrintfA for WinCE. * misc.c (GC_abort): Try to invoke MessageBoxA() dynamically (Win32 only) if DONT_USE_USER32_DLL is defined. * misc.c (GC_abort): Duplicate msg to GC log file (for Win32 and WinCE). * misc.c (GC_abort): Use a more user-friendly abort if NO_DEBUGGING (Win32 only). * os_dep.c: Include "atomic_ops.h" only if MPROTECT_VDB (and THREADS). * os_dep.c (detect_GetWriteWatch): Use TEXT() for GetModuleHandle (for Unicode support); check GetModuleHandle() result. * tests/test.c: Don't define assert for WinCE (since may be redefined by "assert.h" included from libatomic_ops). * tests/test.c (FAIL): Define as ABORT for all targets (except for PCR). * tests/test.c (n_tests): Don't use AO_t. * tests/test.c (check_heap_stats): Don't cast n_tests. * tests/test.c (inc_int_counter): New function (for n_tests atomic incrementation). * tests/test.c (run_one_test): Test GC_memalign() for all targets. * tests/test.c (run_one_test): Avoid unbalanced brackets in #if-#else-#endif blocks. * tests/test.c (run_one_test): Replace AO_fetch_and_add1() and private LOCK/UNLOCK with GC_call_with_alloc_lock(inc_int_counter). * tests/test.c (check_heap_stats): Replace "if (sizeof(char *) > 4)" with "#if CPP_WORDSZ == 64" to suppress "unreachable code" compiler warning. * tests/test.c (WinMain): Set cmd type to LPWSTR (for WinCE "UNDER_CE" mode); else use LPSTR type (for Win32 and WinCE). * tests/test.c (thr_window): Replace "L" string prefix with TEXT(). * thread_local_alloc.c: Check THREADS is defined (to prevent other compiler errors and warnings otherwise). * tests/test.c (WinMain): Recognize GC_NO_DLLMAIN macro (for GC_use_DllMain()). * (GC_NO_DLLMAIN, DONT_IMPORT_GETCURTHREAD): Add the comments for. * win32_threads.c (GC_register_my_thread_inner): Recognize DONT_IMPORT_GETCURTHREAD macro. * win32_threads.c: Recognize GC_NO_DLLMAIN macro (to exclude DllMain support if needed). * win32_threads.c (GC_NO_DLLMAIN): Define implicitly if DllMain thread registration is unsupported for a given configuration. * win32_threads.c (GC_use_DllMain): Update the comment; refine ABORT message. * win32_threads.c (GC_use_DllMain, GC_started_thread_while_stopped, GC_register_my_thread_inner, GC_lookup_thread_inner, GC_delete_gc_thread, GC_allow_register_threads, GC_lookup_pthread, GC_push_thread_structures, GC_stop_world, GC_push_all_stacks): Check for GC_NO_DLLMAIN. * win32_threads.c (GC_Thread_Rep.tm_in_use, GC_attached_thread, DllMain): Don't define if GC_NO_DLLMAIN. * win32_threads.c (GC_stop_world): Declare "i" and "max" local vars only if not GC_NO_DLLMAIN (to suppress compiler warning). * win32_threads.c (GC_mark_thread, start_mark_threads): Use CreateThread() instead of _beginthreadex() for WinCE. * win32_threads.c (MARK_THREAD_STACK_SIZE, WINCE_MAIN_STACK_SIZE): New macros defined (used by start_mark_threads(), WinMain()). * win32_threads.c (GC_thr_init): Exclude parallel-specific code on WinCE for now (since getenv(), GetProcessAffinityMask() and SignalObjectAndWait() are missing on WinCE). * win32_threads.c (GC_thr_init): replace GetModuleHandleA() with GetModuleHandle(); replace CreateEventA() with CreateEvent(); use TEXT() macro (for Unicode support).

# -DGC_PREFER_MPROTECT_VDB Choose MPROTECT_VDB manually in case of multiple
# virtual dirty bit strategies are implemented (at present useful on Win32
# to force MPROTECT_VDB strategy instead of the default GWW_VDB one).
+# -DGC_NO_DLLMAIN (Win32+DLL only) Exclude DllMain-based thread registration
+# support.
+# -DDONT_IMPORT_GETCURTHREAD (Win32 only) Use MS hard-coded thread-self
+# pseudohandle value (-2) instead of linking (or binding) to a real
+# GetCurrentThread() func; mostly useful on WinCE unless "UNDER_CE" mode.
