I don't think cygwin and mingw are the same thing
(http://www.mingw.org/node/21); we compile libotr and
pidgin-otr for Windows using mingw.  The Makefile.mingw for that
suggests that building a DLL is:

$(CC) -g -shared file1.o file2.o file3.o -o output.dll -lwhatever

where $(CC) is the mingw compiler.

So you could either get libotr to build under Visual C++ (which I think
the Trillian plugin author did:
http://trillianotr.kittyfox.net/downloads.php ), or build a libotr.dll
under mingw, and link to it with Visual C++ (perhaps less likely to
work).  Also see the Miranda OTR plugin:
http://addons.miranda-im.org/details.php?action=viewfile&id=2644

All of the above come with source, so there should be good info in there
somewhere.  Certainly "sample code of a Microsoft windows program
communicating with libotr", at least.

Of course, if the authors of either plugin want to weigh in themselves
on this thread, even better.  :-)
