Im not sure exactly what you mean. The gcc `-shared' option compiles shared 
objects (in this case dll's). If you mean something like `gcc -shared foo.o 
bar.o ...' then gcc expects object code.

There's a section (few links at the bottom) in the online documentation 
(http://cygwin.com/docs.html) which goes through how to create dll's.
