Re: can't build gnustep-base on cygwin

[Paul Forgey]

Well, that may have built the base library, but there seems to be more going 
on.  (I temporarily used --disable-xml to get past my other problem)

gnustep-gui-0.9.4 needed a similar modification in its 
GNUmakefile.postamble, however the components using it don't seem to find 
the symbols:

Linking bundle libgmodel ...
dllwrap: no export definition file provided.
Creating one, but that may not be what you want
./shared_obj/IMCustomObject.o(.data+0x348):IMCustomObject.m: undefined 
reference to `___objc_class_name_NSView'
./shared_obj/GMAppKit.o(.data+0x2428):GMAppKit.m: undefined reference to 
`___objc_class_name_NSApplication'
[and a bunch more]
collect2: ld returned 1 exit status
dllwrap: gcc exited with status 1
