I'm pretty sure that's not intentional design. Maybe it is, but undocumented. I've seen several instances of bogus build infrastructures doing wacky things such as libtool link cc -o somelib --export-symbols a.def ... or libtool link cc -o prog a.c a.o in both cases, this 'works': in the end link command, the extra stuff simply gets ignored. So in the first case, --export-symbols which is a mispelled -export-symbols gets ignored. And in the second case, the extra copy of the c file gets ignored. I'm pretty much surprised, I thought that in general, whatever you passed to libtool that it didn't know about it would just pass it along to the linker stage. At the very least, I believe that simply ignoring those extra arguments is very dangerous... in the first case, you end up having a library that exports every symbol where you thought you only were exporting some symbols!
