Yes, of course it will work if the main application is a cygwin app.
Since there are all sorts of DLLs in /usr/bin, you can be pretty sure
that this will work.

Dweui?  Why do you think I'd suggest something that doesn't work.  Again,
of course it works.  The cygwin and mingw compilers are very close to
being the same thing.

Linking Borland objects with gcc objects is another matter entirely.
There is no guarantee that this will work either.

It sounds like you really want to be using mingw.
