support for non-standard C compilers (without fopen, FILE*, ...)

[Steffen Dettmer]

Hi,

recent versions check if $CC supports fopen, FILE* and so on. This
breaks environments that don't have <stdio.h> / libc.a.

Wouldn't the autoconf way to be to /* undef HAVE_STDIO_H */ but leave
the source code to handle this instead of aborting?

Is it possible to writing something in configure.in to keep the old behavior?
