- [ From the Author: ]
-
- I have been informed of a major problem with my 'xwps' program (which
- has been dubbed 'xwps3' by our moderator) which will cause it to
- fill filesystems with NULLs on little endian machines (i.e. VAXEN and
- VAXStations). It seems that a little piece of code left over from the
- translation from 'xwd' causes major problems.
-
- The original code (xwd) had to translate to big endian form on little
- endian machines in order to generate a common bitmap format file. It
- doesn't even get invoked on big endian machines so I never questioned
- it. Here's the context diff.
