But programs compiled with -mno-cygwin don't use cygwin1.dll (which contains
newlib, which contains the stdio functions). -mno-cygwin programs will use the
msvcrt.dll runtime -- which has its own implementations of the stdio functions.
Are you saying that msvcrt's version of tmpnam/tmpfile are broken? If so,
that's not really our problem...
