Fair enough.  You did mention "gcc -mno-cygwin", though, and didn't
include the versions of the various gcc packages.

No, you were building console applications using a MinGW cross-compiler
under Cygwin.  Those applications were compiled for MinGW.  You can't link
MinGW apps with Cygwin libraries (well, you can, but not without some
painful contortions).

If you really wanted to build a Cygwin console application, you'd need to
omit -mno-cygwin.

You can build a console application that would depend on Cygwin.  And it
could be linked with Cygwin1.dll.  If you want to build a pure Win32
application (i.e., one without the dependence on Cygwin1.dll), you won't
be able to link Cygwin libraries into it.

To answer your question, you cannot use the Cygwin popt package for what
you want, since that provides a library dependent on Cygwin1.dll.  You can
probably build a popt library from source under MinGW (i.e., use "gcc
-mno-cygwin" to build the popt library as well) -- this had to be done for
some popular libraries, see the mingw-bzip2/mingw-libbz2_1 packages, for
example.  The popt library may need to be ported to MinGW.

HTH,
	Igor
