Guys,
Thank you all for your replies. Just to let you know that I figured out what
the problem was, and (surprise-surprise) it had nothing to do with perl or
cygwin at all.
It was the source string. What I'm doing is making a Perl socket server process
parts of an html document pased by a client (parts are passed). I have several
versions of client, for different platforms. Well, after I switched from
ActiveState perl to Cygwin perl I also started testing another client (a BHO
for Internet Explorer). Since it does the same stuff the old client did, and by
the looks of it delivers what it should, I didn't suspect it. What it does is
simply pass a part of the BODY content to the server. But, for some strange
reason, IE completely changes the HTML source of the document while loading it
in it's (IE's) DOM. So, the body I would retreive was not the same as the one
in the HTML source. (::anoyed;)
Just to mention for the record: the reason to switch from the ActiveState Perl
to the Cygwin Perl was that the Active's "fork" stoped working after I
installed the SP2 for XP.
