The two files do not match this criteria.

The 4 tools needed to generate these files are written in Ada, each
one has only one source file, and they compile in under a second on my
low end PC). If there are no objection, I'll propose a patch to add
their automatic generation in the Makefile, and they will be generated
in the build directory (by using the build compiler like many other
source-generating tools in the GCC build process). (2000 Paris time
since I need to go to work now :).
