Hi,    :-)

I personally could probably try later if you really really needed me
to, but I've never built GDB before so I'm a little hesitant.
Hopefully Andris can squeeze in a compile or two for you.   :-)

It's supposed to be much faster this way (e.g. Cygwin -> 30% speed increase=
).

Wow, you sound exasperated! Yes, it's a very annoying bug, and
apparently it's existed since 2004 (hi, Gordon!). No fix yet (Bash
source is confusing!), but we do mostly know where the problem lies.

For now, I suggest the wonderful workaround of putting "( " and " )"
around the "return $ac_retval" portions. That seems to make it work
for DJGPP Bash, at least. (I guess you didn't notice my similar issue
when ZILE upgraded to AutoConf 2.64, heh.)
