The following bug has been logged online:

Bug reference:      1584
Logged by:          Benjamin Reed
Email address:      ranger@befunk.com
PostgreSQL version: 7.3.9
Operating system:   Mac OS X 10.4.0 ("Tiger")
Description:        undefined symbol _tas
Details:

Something has changed between 10.3 and 10.4; my PostgreSQL 7.3.9 Fink
package builds just fine on 10.3, but fails on 10.4 with:

gcc -no-cpp-precomp -g -O2 -fno-strict-aliasing -Wall -Wmissing-prototypes

/usr/bin/ld: Undefined symbols:
_tas

I've found some references to similar issues, but have been unable to figure
out how to apply them to the current situation.

Perhaps Apple stopped defining __APPLE__ ?  Or switched from
__ppc__ to __powerpc__ ?  But in any case, updating to PG 7.4
or later should make the problem go away.  If you really don't
want to move off 7.3, look in src/backend/storage/lmgr/s_lock.c.

Yeah, I got that far, but was having trouble backporting the 7.4 bits to
7.3.

The package really only exists for people with pre-existing installs; we
have packages for 7.4 and 8.0 as well.

The strange thing is, it *seems* like both __ppc__ and __powerpc__ are
defined, and __APPLE__ is definitely defined.

I'm having a really hard time narrowing down what's missing.

Hmm, then maybe Apple changed something about the assembler syntax,
such that 7.3's "asm" code is failing to define a global symbol?
