Actually, there isn't any non-portable stuff happening regarding
dates. The _strptime routine is supposed to see 2001-2-29 and realize
that you really mean 2001-3-1. For some reason, the code works pretty
much everywhere else, but HP-UX and VMS. Where the exact failure is,
I haven't found exactly, but once I get off my lazy backside, I'll
have an answer.
