evil-qemacs/input.c
Charlie Gordon d4d6f8a0f3 fixed some configure issues for mingw compile under cygwin
added CONFIG_MMAP to control availability of memory mapped files
added CONFIG_DOC to control doc rebuild
use state variables to control file mmapping and loading
default limit of 512MB for loading file
try and load the file upon mmap failure
do not use alloca in CONFIG_WIN32
use CONFIG_WIN32 instead of WIN32
update Makefile to enable win32 build under cygwin (dumps core)
renamed mouse_event to prevent compile warning
patched unix.c util.c win32.c to enable WIN32 compile
fixed kmap.c to load mapping files when mmap fails or is unavailable
