Compiling guile-2.2.4 for mingw

[Christoph Buck <christoph.buck@smartoptics.de>]

Hi!

Currently i try to compile guile-2.2.4 under mingw64 bit. I had some
minor issues in the c source code which i managed to fix by applying
some of the patches from https://github.com/mkeeter/guile-mingw. Namely 

1) 0003-winsock-compat.mingw.patch
2) 0004-start_child.mingw.patch

Now i am at the point where i have a working guile binary and the helper
scripts in the meta directory. But at this point the boostrapping fails
with the following error:

I have no idea what might be wrong here or how to fix this problem. Does
anbody have an idea?
