What?!?  So, I should do this:

if( fname ) {
	fp = fopen( fname, "r" );
	if( !fp ) {
		fprintf( stderr, "oops.  No filename here at line %d.\n", __LINE__ );
		exit( ENOENT );
	}
} else {
	fprintf( stderr, "oops, didn't pass a filename.\n" );
}

That's ridiculous.  The librarys are supposed to do this sort of thing
for you, so _you_ don't have to do it every time you fopen.  It's
certainly not going to slow you down to a crawl... how much
time-critical code have you written that depends on the speed of fopen?
