This is also solveable by setting a strategic symlink from libc.so -> /usr/lib/compat/libc.so.4 in the f95 backend's search path. Does it do a "gcc -o a a.c -L /usr/local/lib/f95 -lf96 -lm -lc" or something like that? If so, you can put the libc.so symlink in there. I assume that the generated code doesn't contain #includes... If it does you'll also need to do something about that so that you get the right #includes. libf96.so is a 4.x binary. Even if it wasn't for __sF, you should be compiling with 4.x libraries and (if needed) 4.x headers, because you have parts of the 4.x stdio.h embedded in libf96.so.
