Removing -mcpu=970 got rid of the #define bool bool, among other
things, which allowed the configure to go through without modifying
any code. The make still fails with what looks like identical errors.
The only flag I'm now specifying in addition to a vanilla configure,
is the -arch ppc64, which I believe is required for 64-bit.

./configure --prefix=/usr/local/pgsql --enable-thread-safety CFLAGS='-
O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -Wdeclaration-
after-statement -Wendif-labels -fno-strict-aliasing -arch ppc64' --
without-readline --without-zlib

Errors are, again, the same as before:
../../../../src/include/storage/s_lock.h:806:2: error: #error
PostgreSQL does not have native spinlock support on this platform. To
continue the compilation, rerun configure using --disable-spinlocks.
However, performance will be poor. Please report this to pgsql-
bugs(at)postgresql(dot)org(dot)
