(Mostly improves LLP64 support.) * backgraph.c, checksums.c, dbg_mlc.c, finalize.c, mark.c, misc.c, reclaim.c: Changed some int and long type to word or size_t (and vice versa where appropriate) * gcj_mlc.c, include/private/dbg_mlc.h, include/private/gcconfig.h, include/private/thread_local_alloc.h, mark.c, misc.c, thread_local_alloc.c, win32_threads.c: Added intermediate casts to word type when casting from int to pointer (or pointer to int, or data pointer to code pointer) - just to remove the corresponding compiler warning. * ptr_chck.c (GC_is_visible): cast int const to word type to prevent left shift overflow. * os_dep.c: change the type of GC_mem_top_down global var (containing a flag) to DWORD. * include/gc_config_macros.h: define GC_SOLARIS_THREADS if GC_THREADS is defined on SunOS x86_64. * misc.c (GC_init_size_map): Ifdef out GC_ASSERT as a workaround for VC++ 2008 amd64 (v15.00.21022.08 for x64) compiler bug (the compiler gets hung if invoked with -Ox -D ALL_INTERIOR_POINTERS -D GC_ASSERTIONS) * backgraph.c: cast GC_gc_no value to unsigned short when assigned/compared to height_gc_no field of back_edges. * os_dep.c (GC_remove_protection): Add ARGSUSED. * win32_threads.c (GC_thread_exit_proc): Remove unused local var. * mark.c (GC_check_dirty): Move declaration out of func body.
