In src/Makefile.am, LDADD contains "$(top_builddir)/src/libgengetopt.la". However, the rule in the generated Makefile to build that library is just called "libgengetopt.la" -- if you specify the full path, make won't see the dependency.

As a result, if you build gengetopt with "make -j8" (or similar), it's possible for make to try to compile gengetopt before the library has been built, and it'll then fail. If you just say "LDADD = libgengetopt.la", the dependency will work properly.

(I've not checked if there are any other instances of this in the Makefile.ams, but it's probably worth a look.)
