I posted this problem to the list some time ago and having received no
replies thought it was specific to me, obviously it isn't. All of Sergeys
cygwin.dlls exhibit this problem with "configure" on  W95. By a process of
elimination I have traced it the modification of "fork.cc" in the very
first set of changes posted by Sergey (called "itimer.tar.gz" on his web
page). I can include all the other modifs. from this set and the
regenerated cygwin.dll executes "configure" faultlessly. If I then
regenerate with the new "fork.cc" I get the problem with "sh" crashing the
system. That's as far as I've got for the moment. The original patch to
fork (see below) is considerably updated in subsequent patches from Sergey
but none of them seem to solve this particular problem. Please feel free to
comment if you have any ideas but don't expect a rapid reply as I leave on
two weeks vacation tommorow :^)
