ld_so_aix.patch

diff

Allow multiple '-bI:...' arguments. The special processing -- i.e. 
default to ./python.exp if no import is given and prepending '-Wl'
if necessary -- is only done for the first occurrence.

multiprocessing_aix.patch

For reference see 
	http://bugs.python.org/issue3876
and	http://www.velocityreviews.com/forums/t638521-builing-python-26-on-aix-52.html
This might be fixed in Python 2.6.1. Watch.
Extended with definition for _CMSG_ALIGN for SunOS.
Modified setup for SunOs before 5.10 as well, has no sem_timedwait
