can't build gnustep-base on cygwin

[Paul Forgey]

Running cygwin 1.5.11-1 and trying to build gnustep-base 1.10.0, I'm running 
into the following build error.  It's failing because there is no occurance 
of "_class_name_" in the resulting list.  What exactly is the build process 
attempting to do?   I see _class_name_ in the nm output, but not if I filter 
it with the first grep statement.  I do, however, see quite a few symbols 
starting with ___objc_class_name_ with a 'U' instead.  Does this mean for 
some reason the definitions are never actually being built?

cat win32-def.top > libgnustep-base.def
nm [long list of objects] | grep '^........ [T] _' | sed 's/[^_]*_//' > 
_tmp.def
cat _tmp.def | grep "_class_name_" >> libgnustep-base.def
