I tried to reproduce this on my own Fedora 14 box, and couldn't.
I cd'd to src/interfaces/ecpg/preproc and did several repetitions of

make maintainer-clean
make -j

and every time, make carefully waited until bison was done before
launching the compiles of preproc.o, parser.o, and the other files
that are declared to depend on preproc.h.

I *can* reproduce failures if I do the same thing one directory level
up, in src/interfaces/ecpg. But those are caused by the other sub-makes
not waiting for include/ecpg_config.h to get built. Fixing that is
beyond my level of make-fu.

This is with make-3.82-3.fc14.x86_64 ...
