Nonetheless, it would seem that ActiveState Perl is the thing with the bug in
it. Not being a cygwin program, a change to the cygwin dll could hardly affect
ActiveState Perl's behaviour, could it?
Well, it shouldn't of course, but I can imagine one way in which it could.
Bear in mind that running inside the bash shell - unlike if you were to just
try your test from a cmd.exe shell - has one major difference: the $PATH setting
includes the cygwin bin directories at the front.
Now, given that cygwin includes its own distribution of Perl, which presumably
is also called "perl.exe", we have a potential for clashes here.
FWIW, running the example that you gave with cygwin perl doesn't produce a DOS
box. I'm not surprised that AS perl wants to have its system commands run in a
dos box, as that's the only system it knows about. OTOH I see Jason's post
saying that he can't reproduce your problem. Therefore I suggest the two of you
compare $PATH settings, in particular which order AS perl and cygwin's bin
directories occur in both your $PATHs, and that may give us some further
Can't think of a witty .sigline today....
