Like a new variable $ac_presub, that is executed as

  sed "$ac_presub" | sed "$extrasub; other config.status substitutions"

?  I think this is what I like the most.  Does the following plan make 
sense to you as Autoconf maintainer? (CCing autoconf@gnu.org).

The patch should be easy, so we can get ac_presub in 2.65 and upgrade 
GCC from 2.64 to 2.65 as soon as it gets out.  The rationale is that 
anyway 2.65 is going to have only minor bug fixes besides the two Erlang 
patches, some of them too invasive to place them in override.m4.

Regatding the timing of Autoconf 2.65 the DJGPP issue is pending, but it 
can probably be fixed only in DJGPP rather than in autoconf, so it 
wouldn't prevent releasing Autoconf 2.65 (in fact, having the 
possibility to mention it in the release notes would be a reason to 
release 2.65 sooner).
