Having seen you guys meet this problem, I have not upgraded.

Today I built the prerelease under NT both as-is and also with the Win98
mods from Malcolm.

Under Nutcracker/DEC X-Server, using Cygwin 1.1.8, I have no troubles with
the standard build.

With the W98 modified version I get exactly the behaviour just described by
Eric - the monitor shows and immediately exits.

Regarding my earlier posts about read() and Cygwin binary mounted drives, I
realised that if open() is called with O_BINARY as the second argument, it
should fix the problem.  I'll try it out this weekend if I can get near my
computer.

I am trying to get the font building program "splitfonts" to work under
Windows too.  The popen call seems to cause problems.
