I'll take a look at that, I'm sure it's more complete than my
implementation.  Is it part of the standard distribution?

OK, so I'm doing it right now, great :-)  Back to the original question -
is there some way I can get "AC_CONFIG_HEADERS" to work with both automake
1.7 and automake 1.5, or something that will give me the same
functionality?  Or do I need to establish a new minimum version of automake
and tell my developers to upgrade?

Then where do people get them?  I'll have to do some googling for past
discussions about this I guess.

And/or autotools are gaining popularity.
