Okay, I know this isn't directly related, but you guys seem to keep
thinking 2.05b is old and unused, and even I suspected it was more
widespread and probably not buggy on other OSes. At least now I know
for sure (see below).

Well, I'm out of town (90 miles north) with good ol' Dad for a week.
I'm actually on his Mac laptop (iBook G4), which is OS X 10.3.9
Panther PPC (I think). Here's a quick test result from the Terminal
(though no GCC installed, no surprise there):

000-00-00-000:~ blah$ cat gordon.sh

   echo Calling out to the world...
   echo `uname`
   echo Preparing to meet our maker!

000-00-00-000:~ blah$ uname -a
Darwin 000-00-00-000.client.mchsi.com 7.9.0 Darwin Kernel Version
7.9.0: Wed Mar 30 20:11:17 PST 2005;
root:xnu/xnu-517.12.7.obj~1/RELEASE_PPC  Power Macintosh powerpc
000-00-00-000:~ blah$ ./gordon.sh
Calling out to the world...
Preparing to meet our maker!
000-00-00-000:~ blah$ echo $BASH_VERSION
000-00-00-000:~ blah$

(edited for a bit of anonymity, God knows why ...)

Even without DJGPP installed here, I'm pretty sure the "bug" on DJGPP
(pre-2.05br3) was that it crashed instead of continuing to the
"Preparing ..." text. Hence it's not a Bash bug, only a DJGPP no-fork

P.S. Yes, I know, it's not exactly the newest OS X (10.6.1), but hey,
it exists, and it's only a five-year-old laptop, I think. The worst
part is that you have to upgrade the OS for most apps to work these
days. And Snow Leopard drops support for PPC, oh well.   :-P
