well, my ac-macro started out as some sed-lines in the makefile, but I
didn't wanted to copy it from project to project exchanging the prefix
which was always derived from the package name.

of course, one could extend automake to see this generation and add it
the appropriate lines to the makefile.in, but I guess that adding the
output-file to the list of ac_output should be good enough to have it
remade everytime a reconf is needed.

so, it still boils down to adding some lines to config.status, and 
the only problem I see is to rewrite the macroitis currently being
used, since the config.status must be a plain shell script, all the
m4 specials must be removed from the code. And Clinton, do I read
it correctly that you have some experimental code about it, could
you just show that?
