#R668: Windows 2000 Lock File Creation Error

This was a tricky one.  While the error was ultimately because
he was specifying a non-existant directory in defaults.nh, the
error message lead me to the wrong area until I traced through
with a debugger.

It turns out that an fqn buffer was being re-used before it
was finished being used with the original information in
sys/share/pcunix.c, so the error message listed the
wrong file!

This adds one more buffer and fixes the problem.
Note that it could only affect plaforms with
PREFIXES_IN_USE defined  (NOCWD_ASSUMPTIONS
or VAR_PLAYGROUND)

It also alters the WIN32 error message to give them a
hint as to what the problem might be.
