* Makefile.in: Add support for new malloc.o and renamed malloc_wrapper.o. Use -fomit-frame-pointer for malloc.o compilation. * malloc_wrapper.cc: New file. Rename from malloc.cc. Add support for more malloc functions. Eliminate export_* calls. Just use straight malloc names. Remove unused argument from malloc lock functions. * cygwin.din: Just export straight malloc names. Add malloc_stats, malloc_trim, malloc_usable_size, mallopt, memalign, valloc. * dcrt0.cc (__cygwin_user): Eliminate export_* malloc entries. * fork.cc (fork_parent): Remove unused argument from malloc_lock argument. * malloc.cc: New file. Doug Lea's malloc v2.7.1. * cygmalloc.h: New file. * include/cygwin/version.h: Bump API_MINOR. * sync.h (muto::acquire): Use appropriate number for regparm attribute. (muto::reset): Ditto. (muto::release): Ditto.
