It can't be that difficult; lisp is designed for this type of
manipulation.

The dependencies absolutely must be generated automatically. Whether
this should be done by the byte-compiler or a separate script isn't clear
(yet). Such a separate script could probably be run in temacs, creating
the dependencies very early in the build process.

"Sporadically", for me, means once a month or once every two months.

One kind of "peer review" we could do is doing a build test as part of
the commission process. This might be a bit heavy on server CPU time.

For what it's worth:
32-bit;
Linux acm 2.6.8 #7 Wed May 23 18:12:53 BST 2007 i686 GNU/Linux.
glibc: don't know, how do you display the version number?
gcc (GCC) 3.3.5 (Debian 1:3.3.5-13)
I can't honestly see that it's worth that much. Won't Emacs compile with
pretty much any Linux version, any GCC and any GLIBC?
