[PATCH] Win32 errno a little bit safer

Hello, i just reviewed the win32 errno patch and i saw that maybe i didn't
really played it totally safe in my last suggestion, the system table might
pick up the msg but not the netmsg.dll, so better try both.
I also added a hex printout of the "errno" appended to all messages, that's
nicer.

If anyone hate my coding style, or that i'm using goto constructs, just tell
me, and i'll rework it into a nested if () thing.

Patch attached.

Magnus
