Sorry for being confuse.

I agree your solution is the most appropriate for their issue, but the
general question I was trying to address was that of hooking commands
to AC_CONFIG_FILES, AC_CONFIG_HEADERS.  Some people want some commands
to be ran when the header is created.  I was merely looking for the
syntax to code into Autoconf.

But I'm now tempted to drop this, until someone comes with an actual
need.
