| cc1: all warnings being treated as errors

The code has two problems:
1) it assumes time_t is unsigned
2) it assumes time_t is the same as unsigned long

1) rarely is true
2) is not true on 32bit architectures which have a 64bit time_t

Fix by appropriate casting and an updated printf format specifier.
