[Pythonmac-SIG] First experiences with the python24-fat tree.

[Ronald Oussoren]

test_email is failing, this is due to a bad checkin: the files in Lib/ 
test/data should be checked in as binary files and are not

The attached python2.4-readline-searchpath.patch makes sure we pick  
up libreadline.a from LDFLAGS in preference of the system  
libreadline.dylib

The attached patches python2.4-weaklinking.patch makes it possible to  
run 'regrtest -uall' on OSX 10.3 systems. IMO this patch needs work,  
I'd be surprised if it were accepted into the python repository as is.

What I don't quite understand is that the latter patch doesn't quite  
work: the i386 contains weak links to fstatvfs and other 10.4-only  
symbols, but the ppc version does not. A small test program does work  
correctly.

testfile.c:
#pragma weak fstatvfs

#include <sys/statvfs.h>
#include <stdio.h>

int main (void)
{
         printf("%p\n", fstatvfs);
         return 0;
}
// EOF

Compile this with 'MACOSX_DEPLOYMENT_TARGET=10.3 gcc -arch i386 -arch  
ppc -o testfile testfile.c -isysroot /Developer/SDKs/ 
MacOSX10.4u.sdk'. 'nm -arch ppc -pm testfile.c | grep statvfs'  
clearly shows that statvfs is weakly linked. Yet 'nm -arch ppc -pm  
Modules/posixmodule.o' shows a hard link and 'nm -arch i386 -pm  
Modules/posixmodule.o' shows a weak link again. What's even stranger  
is that weaklinking works properly again if I create a PPC only build  
by first configure-ing for a universal build and then removing '-arch  
i386' from the toplevel Makefile.
