New submission from Marc-Andre Lemburg <m...@egenix.com>:

A typical build line looks like this:

gcc-4.0 -c -fno-strict-aliasing -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch 
ppc -arch i386 -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes  -I. 
-IInclude -I./Include -isysroot /Developer/SDKs/MacOSX10.4u.sdk   
-DPy_BUILD_CORE -o Python/codecs.o Python/codecs.c

With older Xcode releases, the above is known not to work at all: gcc simply 
gives up and raises an error. With the latest Xcode available for 10.3 (last 
release + all patches), gcc accepts the extra options, but it's not clear 
whether the resulting code will work... mostly due to #9046: Python 2.7rc2 
doesn't build on Mac OS X 10.3.

The two issues could also be connected.
