Um. I was talking about a branch to *rewrite configure.in from
scratch*, including an irrevocable shift to the new facilities
provided by 2.50. Not a branch to deal with issues that turn up when
people start using 2.50 to compile the existing configure script.
Those can+should be dealt with on the trunk.
It would also be a good place to deal with mucking out the last few
remnants of Cygnus configure in the gcc directory, as Phil suggested.
The x- and t- fragments, the related Makefile.in gunge, the places
where configure does actual work so you can't just rerun
./config.status to regenerate the build tree, the inability to use
@var@ substitutions in Make-lang.in. Things like that.
As for the 'way too much fuss' ... you have to understand gcc has a
configuration scheme with a 14 year history (gcc 1.0 was in 1987) and
tons of dust in the corners. The fuss is largely over our own
iatrogenic problems, not the ones caused by autoconf.
