So how do I cross-compile with CygWin to MinGW32? I finally managed
to get the thing compiled, but after "configure" I had to add
-mno-cygwin manually to the Makefile's "CC = gcc" statements and
also had to manually edit some config.h files.

Probably I already have to tell "configure" to use -mno-cygwin, but
how? I am still not all too familiar with CygWin and configure ...

Have you looked at my howto for building mingw cross compiler? That may
answer your question.

See http://www.xraylith.wisc.edu/~khan/software/gnu-win32/

I've never tried building under cygwin, but in theory it should work just
as well as under Linux or other well supported Unix'y hosts.

Mingw doesn't provide a posix emulation, so I wouldn't expect GNU
tools to build with it.  I think our expectation is that the
development tools would always be built with cygwin, and would
cross-compile to mingw.

B20.1: how to build for MinGW32?

[Kai-Uwe Rommel]

I am trying to rebuild the binary utilities of B20.1 (see my
previous message for the reason).

While I can run configure and recompile the binary utilities
(and libiberty, bfd and intl which are needed, too) with
CygWin without significant problems, I can't see how I can
recompile the binary utilities for MinGW32.

I found the -mno-cygwin32 option but when I attempt to compile with
that, I already fail in libiberty.

Since I can't find notes about that in the docs, here is my
question: what is the official way of recompiling the code for
MinGW32?

Mingw doesn't provide a posix emulation, so I wouldn't expect GNU
tools to build with it.  I think our expectation is that the
