BTW, I notice some suspicious-looking behavior with -j:

$ make -j8 -s
Writing fmgroids.h
Writing fmgroids.h
Writing postgres.bki
Writing fmgrprotos.h
Writing fmgrtab.c
Writing schemapg.h
Writing postgres.description
Writing postgres.shdescription
Writing fmgrprotos.h
Writing fmgrtab.c
...

Why do fmgroids.h, fmgrprotos.h, and fmgrtab.c now get mentioned
twice?  I suspect there is something broken about the parallelization.
If indeed multiple instances of gmake are writing these files
concurrently, that's likely to result in irreproducible build failures.

I've pushed a fix for this.

Seems to fix the problem for me --- thanks!
