Problems building gnustep-base on cygwin

Dear all,

I have some problems building gnustep-base on cygwin.
I inititally had some problems with configure not finding libxml2
which is present on my system. I solved that using conigure
--disabel-xmltest.
Then I had some problems with ld not finding -lcallback. Apparently
"make install" for ffcall had installed it in  a location that
configure isn't looking for. I fixed that by copying libcallback (and
the other ffcall libraries) to /usr/lib.

No I get the following error and I don't know what to do about it. I
noticed a similar post to this list, but it didn't help me much.

Any ideas ?
