Here is my proposal. I've tested it by s/configure.in/configure.ac/g
the test suite, and it works. I have not tested with a real package
yet though.
I was not sure where you would have preferred that automake detects
configure.ac vs configure.in: I've done this in scan_autoconf_files
(former scan_configure), but maybe the top level would have been
better.
I really apologize for the length of the patch, but I don't have
enough experience to know a priori how to segment my patch by stages.
So this is the whole stuff. It shouldn't be too hard to read though.

Index: ChangeLog
from Akim Demaille <[EMAIL PROTECTED]>
Let Automake support `configure.ac'.
* automake.in: In the comments, prefer `configure.ac' to
`configure.in'.
When using &am_conf_error, don't repeat `in configure.in', since
the function already reports it.
When referring to `configure.in' use `$configure_ac' instead.
(configure_ac): New global variable.
(scan_configure, scan_one_configure_file): Rename as...
(scan_autoconf_files, scan_one_autoconf_file): this.
(scan_autoconf_files): Compute $configure_ac.
(transform): New function.
(handle_configure): Use it to transform CONFIGURE_AC in
`remake.am' and in `remake-hdr.am'.
(common_files): Also consider `configure.ac'.
Use consistently single quotes.
* aclocal.in (configure_ac): New variable.
Use it.
* texi-vers.am: Depend on CONFIGURE_AC not configure.in.
* remake.am: Likewise.
* remake-hdr.am: Likewise.
