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?
