OK, I guess my hack to build the correct list of object files to give to
nm was somewhat unreliable... :-(
I just tried to write something cleaner, and it looks like I succeded.
See the attached patch, for libcdio-0.74/lib/driver/Makefile.am. If it
is confirmed to work fine, it can trivially be adapted for other
Makefile.am files...
Cheers,
Nicolas
