Use mmap(2) emulation for buffer text on MS-Windows.
src/Makefile.in (C_HEAP_SWITCH): Get the predefined heap size from configure. (ADDSECTION, MINGW_TEMACS_POST_LINK): Remove, no longer used. src/lisp.h (NONPOINTER_BITS): Modify the condition to define to zero for MinGW, since it no longer uses gmalloc. src/buffer.c: Do not define mmap allocations functions for Windows. Remove mmap_find which is unused. Remove mmap_set_vars which does nothing useful. [WINDOWSNT]: Include w32heap.h. (init_buffer): Always allocate new memory for buffers. src/emacs.c: Remove mmap_set_vars calls. src/image.c (free_image): Undef free for Windows because it is redirected to our private version. src/unexw32.c (COPY_PROC_CHUNK): Use %p format for 64bits compatibility. (copy_executable_and_dump_data): Remove dumping the heap section. (unexec): Restore using_dynamic_heap after dumping. src/w32heap.c (dumped_data_commit, malloc_after_dump) (malloc_before_dump, realloc_after_dump, realloc_before_dump) (free_after_dump, free_before_dump, mmap_alloc, mmap_realloc) (mmap_free): New functions. src/w32heap.h: Declare dumped_data and mmap_* function prototypes. nt/inc/ms-w32.h: Switch to the system heap allocation scheme instead of GNU malloc and ralloc. nt/inc/sys/mman.h: New file. nt/INSTALL: Update for the new build requirements. etc/NEWS: Mention build changes on MS-Windows. configure.ac (C_HEAP_SWITCH) define for different values of dumped heap size depending on 32/64bits arch on Windows. Don't check for pthreads.h on MinGW32/64, it gets in the way. Use mmap(2) for buffers and system malloc for MinGW32/64.
