detecting libcrypt

["David N. Welton" <da...@dedasys.com>]

So, can one of you OpenBSD people try this out for me?

proc configure::lib_has_function { library function } {
    set program {
	int main() {
	    %s();
	    return 0;
	}
    }
    set program [format $program $function]
    set fl [open testconfig.c w]
    puts $fl $program
    close $fl
    if { [catch {
	exec cc -o testconfig testconfig.c -l$library
    } err] } {
	return ""
    } else {
	return "-l$library"
    }
}

puts [configure::lib_has_function crypt crypt]

Thanks,
