ecpg-related build failure with make 3.82

On my Fedora 14 box, make -j3 fails.  I think the below is the
relevant portion of the output.  This has a passing similarity to bug
5665, but I can't for the life of me see what the problem is here.
parer.o depends on preproc.h, which depends on preproc.c; therefore,
parser.o should not be built until preproc.c has been built, but
that's exactly what make is doing.
