Justin,

Thanks for the pointer.  The direct solution here is to remove the line
that includes error.h.  I thought I did that before the copy went to CVS,
but I guess I didn't.  <error.h> was originally included to check on a
condition that never occured, so I removed the check.  <error.h> isn't
needed in the current version.

Markus, would you be so kind as to remove the reference to error.h?  For
some reason my DNS seems unable to find you this morning.  My mail
directly to you bounced immediately.

The code is written to use open, read, write, and lseek, (all POSIX) and I
don't think I can switch lseek to fseek (ANSI) without changing all the
other references to their ANSI counterparts.  If there are ongoing
problems, then I'll do it, but then the same change will be needed in a
lot of the rest of the GRASS code.
