particularly the part about attaching the output of "cygcheck -svr".  You 
haven't said which version of perl you're running, or even if you're 
running the Cygwin perl as opposed to some other version, or what your 
input was, or what the whole script is.  FWIW, I can't reproduce this on 
WinXP Pro, Cygwin 1.5.10-3, perl 5.8.2-1 with the following snippet:

echo "<a href=\"#\" onClick=\"window.open('popBibTex.cfm?aaa&bbb&ccc',ddd,eee)\">kkk</a>" | \
perl -e 'undef $/;$page=<>;unless ($page =~ /<a href="\#" onClick="window\.open\('"'"'(popBibTex.cfm\?.+?)'"'"',/s){print "No match\n";}else{print "Match\n";}'

It prints "Match"...

P.S. BTW, '\C' in Perl REs matches any 8-bit character...
