MS implibs cannot be linked using current binutils ;-)
There is NO support in binutils for COMDAT symbols.
Static MS libraries/objs can be linked using current
binutils, but there are some problems even with that.
combining precompiled static MS libraries/objs (which
assume msv libc/crt functions) with cygwin gcc compiled code
will usually fail, you can't mix runtimes.
Even using mingw32 some of the startup routines
just aren't there. The only way to guarantee compatibility
is to buy a copy of vc++ compile the libc libcmt etc...
using mingw32 gcc (a Major project in itself !-) and
then link using link.exe.

BTW -Ldir -lXYZ will link with dir/libXYZ.a
the second switch is small ell.
you will need to copy or link (ln -s) XYZ.lib libXYZ.a
otherwise ld won't be able to find it.
