Yes, sure.

Yes, does it also work when you change configure.ac and autoreconf?

Yes, hat would be nice.

I'm using gc-6.8 and cannot seem to build a version for Mingw that
includes GC_local_malloc -- that seems to be for linux pthreads only.

Removing this redirect to local, fixes these

    .libs/libguile_2.0_la-alist.o:alist.c:(.text+0x6bf): undefined reference to `_GC_local_malloc'

build errors.

I don't have in it my mingw-runtime-3.14.  If there's a newer version,
I've misses something and would like to hear it.

No, it lacks the AI_* definitions.  I realise that you may not want
to include this just yet, although it "documents" my progress building
it for mingw.

Yes.

More bits in a new thread.

Thanks, greetings,
