Good guess, but the original RE didn't support any variations of 
whitespace, so it wouldn't have matched a multi-line string anyway...  
However, if the OP didn't provide the exact RE he used, he could try 
setting PERLIO=crlf in his environment and see if that helps.

One thing that he may also be missing is that the '/s' flag will retain 
all the characters, even though it runs the RE over one string, so that 
string may (and usually will) contain newlines, which have to be accounted 
for in the RE.

P.S. Oh, and <http://cygwin.com/acronyms/#PCYMTNQREAIYR>, even the list 
address.  Thanks.
