I've written about this at least a few times already, so I won't repeat it.
Essentially, you need to either build the mingw target libraries or get
them out of the mingw32 egcs-1.1 binary package. The target libraries are:
libstdc++.a (C++ runtime), libiberty.a (if you need it for various BSD'ish
but non-POSIX routines such as random); there are also other libraries
such as Tcl/Tk, BFD etc, but most users don't need them. 

You can pick up libstdc++.a and libiberty.a from:
look for mingw-libs.tar.gz. Put these in some directory and you can
either use -L/path/to/mingw/libs or modify specs to include this in
the library search path whenever mno-cygwin is specified.

"gnu-win32-request@cygnus.com" with one line of text: "help".
