Hi!  I haven't tried that, but it should be possible.  I use MinGW under
Debian.

I didn't use any parameter when building under debian.  Did you run into
problems that lead you to use these?

In particular, do you want --disable-shared?  Building a DLL should be
possible.

I think this is the problem: we check if -Wl,--output-def works, and
enable the *.def stuff if it is, but if --disable-shared is used, I
suspect that the linker won't output a *.def file, so the build fails.

To work around the problem, just 'touch lib/libgnutls-26.def' to create
a zero size dummy file.  Then re-run make.

You could try and remove --disabled-shared, then a shared library will
be built and the *.def file will be generated via --output-def.

However, building only static libraries should be supported too, so we
should fix this.  We probably shouldn't even attempt to use --output-def
if we aren't building shared libraries.  I've installed the following
patches.  Could you try tomorrow's daily snapshot?
