That's on my TODO list :)
However fixing the libtool library expansion is very hard. Currently I
am thinking of performing a "hard" replacement of "-lpcre" with
"/target/lib/pcre-4.4/lib/libpcre.dll.a" etc., as using "-lpcre"
yields "/target/lib/pcre-4.4/lib/.libs/libpcre.a" which does not
exist. Additionally this "lib/.libs" path fragment does not appear
anywhere (not even within the libraries) so I have really no idea on
what goes wrong here...

And another *very* important reason to do so is the increased
performance. When running cygwin Ethereal, it runs slowly because of
the slow cygwin interface (Win32 path conversion to *NIX patchs and
the opposite way takes ages).
