DLLD is undefined on Mac OS X because we do not yet know how to build
dynamic libraries on OS X yet. 

"make all" try to build all targets, i.e extgcd-sta, extgcd-dyn and 
libextgcd.dylib. 

extgcd-sta should work fine.

extgcd-dyn cannot be built (we would need libpari as a dynamic library).

libextgcd.dylib should be buildable, but the makefile is not quite right
(it try to build a shared library instead of a sared object and this is
not the same on Darwin).

Try the attached patch (do not forget to rerun Configure).
That might also fix the same problem on cygwin.

Please note that if you interested in building bundle, you should
consider using gp2c-run from the GP2C package.

Cheers,
Bill
