Summary: Support on Mac OS X 10.2

Initial Comment:
Perhaps it is time to officially drop support for Mac OS X 10.2. When I try running the one from the link below I get a segmentation fault. I did some gdb tracking before which is posted on the mactcl list.

Some time ago I did some work on building on my 10.2 box and then running
gdb, and then it didn't crash on the SpinLock anymore, or at least it
crashed on some ATSUI code before that, if I remember correctly. At some
point I gave it up, although it built OK on 10.2. I think I either posted
you directly or via the tcl-mac list. Sorry for my bad memory. There should
be gdb stack traces somewhere.

this is the crash in tclMacOSXNotify.c that has come up on tcl-mac
before?
if yes, as far as I recall, it only affects builds done on 10.4 and
running on 10.2? i.e. builds done on 10.3 or 10.2 work correctly? nothing
to do with 10.2 support as such then, but an issue with  the weak-link
support for OSSpinLockLock etc. in tclMacOSXNotify.c IMO.
I don't think we came to a satisfactory conclusion when investigating this
last time, I no longer have access to a machine capable of running 10.2, so
if you can, please try to debug this further (but don't use the standalone
build, it has no symbols).
The main thing to look at would be the SpinLockLockInit() setup in
tclMacOSXNotify.c, maybe this is not even being called on 10.2 (possibly
due to a pthread_once problem)?
