OK, then the "no-dependencies" in gettext's Makefile.am was innocent.

That's clear, thanks. The reason is thus that some source files which do
  #include "po-gram-gen.h"
got the one in the source dir, wherease the compilation of
po-gram-gen.c used the results of the Bison invocation on 2006-12-16 18:42:42.

po-gram-gen2.h is not the problem, since it occurs only once. The problem is
with po-gram-gen.h and po-gram-gen.c. gettext-tools/src/Makefile.am relies
on automake to DTRT, but it DTWT: it creates the new files in the build
directory. I know the reason why: if a source distribution is installed in a
read-only location, the build in a VPATH should not touch any file in the
source directory. Say the automake theorists.

The result are inconsistent compiles, as you see.

Are you are going to report this to the automake people?
