I'm not sure what more we can do. I have no idea how to write a configure

Something like the following should be ok, but I haven't tested it.
AC_COMPILE_IFELSE([AC_LANG_SOURCE([[
#define _POSIX_SOURCE
#include <stdio.h>
int main () {
FILE *fp;
fp = fopen("/tmp/foo", "e");
return 0;
}]])], AC_DEFINE([HAVE_FOPEN_E], [1],
[Define if fopen(... , "e") exists.])
)
Since the argument is just a string, it will compile fine, since I don't
know of any compiler that tries to parse & check fopen() option strings - it
would have to be a runtime test, and I don't know if all implementations
that don't support the "e" modifier (I think you still need the "r" or "w"
base) will report an error from it, or if some just ignore it.
