Yes, a question. First note that I'm a binutils (l)user, not a
developer so I apologize for being thick. Now the question:
Isn't the functionality you're searching for already in ld given by
the --no-whole-archive options?
gcc -shared -o cygfoo.dll $(OBJ)
-Wl,--out-implib,libfoo.dll.a
-Wl,--no-whole-archive -lbar -lbaz
Or am I missing the point?
