Oups - I actually didn't look so far - readed that same bug hit
GNU/Linux on Super7 so didn't look further...
Since I was in a good mood (Emacs 23 working on my boxes) I took the
liberty to also define GC_SETJMP_WORKS since I saw it next to
GC_MARK_STACK [and ok, I felt lucky...]

So far so good - full build/bootstrapping went fine from latest git
master - basic testing don't show regressions - will see tomorrow if
something fishy pops during work, otherwise looks fine.

In case of need: the compiler used is a gcc-2.9-aix51 on a good old
aix 5.2 - didn't have the courage to try the outdated xlc...

Notes:
* To be able to build emacs with X support (I was really in a good
mood): Had to correct 2 files with "old compilers are grumpy" errors
[0001-gcc-2.9-aix51-020209-compile-fix.patch]
* The actual change I made to src/s/aix-4-2.h
[0002-GC-test-for-AIX.patch]

Regs,
Pierre
