-/** strptime workaround (for oa macos leopard)
- * This strptime follows the man strptime (2001-11-12)
- * conforming to SUSv2, POSIX.1-2001
- *
- * This very simple version of strptime has no:
- * - E alternatives
- * - O alternatives
- * - Glibc additions
- * - Does not process week numbers
- * - Does not properly processes year day
