I finally had some time to work on this and have got (perhaps) a little farther (I compiled with clang, although I get similar errors with gcc). I still these errors:
h:/Source/nsis/sources/gstep-current/svn-libobjc2/block_trampolines.S:113:
Error: junk at end of line, first unrecognized character is `-'
Which I can solve by deleting these lines in block_trampolines.S and
objc_msgSend.S:
Index: block_trampolines.S

Which didn't seem to cause any side effects, but then I ran into the errors
Jerry had below. Based on some googling, I tried to fix the this error by
removing "-fPIC" and defining "-DDLL_EXPORT", but that didn't seem to help.
Finally I just removed this line (sorry, I don't know any assembly):

and the file compiled, but I got an error message later when linking (which
appears related):

I'm still trying to find something that works for that. Also, FYI asprintf and
mkstemp are not defined on MingW, but it's trivial to add a definition for
those (patch attached, although probably in the wrong place).
