* dbg_mlc.c (GC_debug_strdup, GC_debug_free): Output a portability warning if the argument is NULL and GC is in leaks detection mode. * dbg_mlc.c (GC_debug_strndup, GC_debug_wcsdup): New public function definition. * malloc.c (GC_strndup, GC_wcsdup, strndup): Ditto. * mallocx.c (GC_posix_memalign): Ditto. * malloc.c (strdup): Fix string size value; rename "len" to "lb". * mallocx.c: Include errno.h unless WinCE (otherwise include windows.h for Win32 error constants). * win32_threads.c: Define WIN32_LEAN_AND_MEAN and NOSERVICE before windows.h inclusion. * misc.c (GC_init): Register at-exit callback if GC_find_leak (even if GC_FIND_LEAK macro is unset). * pthread_stop_world.c (NACL_STORE_REGS, __nacl_suspend_thread_if_needed, GC_nacl_initialize_gc_thread): Use BCOPY() instead of memcpy(). * pthread_support.c (GC_init_real_syms): Ditto. * doc/README: Update year in copyright. * include/gc.h: Ditto. * doc/README.macros (GC_DEBUG_REPLACEMENT, GC_REQUIRE_WCSDUP): Document new macro. * doc/README.macros (REDIRECT_MALLOC): Update documentation. * include/gc.h (GC_strndup, GC_posix_memalign, GC_debug_strndup): New API function prototype. * include/gc.h (GC_MALLOC, GC_REALLOC): Redirect to GC_debug_malloc/realloc_replacement() if GC_DEBUG_REPLACEMENT. * include/gc.h (GC_STRDUP): Remove redundant parentheses. * include/leak_detector.h (realloc, strdup): Ditto. * include/gc.h (GC_STRNDUP): New API macro. * include/gc.h (GC_NEW, GC_NEW_ATOMIC, GC_NEW_STUBBORN, GC_NEW_UNCOLLECTABLE): Add missing parentheses. * include/gc.h (GC_wcsdup, GC_debug_wcsdup): New API function prototype (only if GC_REQUIRE_WCSDUP). * include/gc.h (GC_WCSDUP): New API macro (only if GC_REQUIRE_WCSDUP). * include/leak_detector.h: Add copyright header; add usage comment; include stdlib.h and string.h after gc.h (unless GC_DONT_INCLUDE_STDLIB). * include/leak_detector.h (malloc, calloc, free, realloc): Undefine symbol before its redefinition. * include/leak_detector.h (strndup, memalign, posix_memalign): Redefine to the corresponding GC function. * include/leak_detector.h (wcsdup): Redefine to GC_WCSDUP (only if GC_REQUIRE_WCSDUP). * include/leak_detector.h (CHECK_LEAKS): Add comment; don't define the macro if already defined.
