This doesn't seem like a good idea. Not rebuilding the output files
also saves recompiling the things that depend on them. For the BKI
files thast doesn't matter much, but for schemapg.h it might be
significant. Certainly, if we move to generating more header files
this way, it WILL be significant. If running the script is cheap (and
it should be), it's better to take that hit rather than recompiling a
whole mess of .c files unnecessarily.
