Better handling of platforms which hide "extended" functionality Some platforms apparently feel -std=c99, which defines __STRICT_ANSI__, should also hide a bunch of function prototypes. This rather sucks. At least try to deal with it. MinGW and DJGPP both have this problem, in particular.

file: improve the file access interface A number of fairly common operations are invoked way too many times, especially when using incbin. Drastically reduce the number of system calls that need to be executed, and use memory mapping to reduce unnecessary double buffering. We could improve this further by leaving files open once used; however, that might run into file count problems on some systems. Still unclear is why we seem to invoke nasm_file_size() twice per pass for incbin. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
