Comment(by was):
I was reading this blog post and it mentions that Apple made some massive
changes to GCC-4.2.x in XCode:
http://dobbscodetalk.com/index.php?option=com_myblog&show=Snow-Leopard-
Changes-to-C.html&Itemid=29
In particular, they added closures to C!
This page talks about weird issues with the new Xcode and GCC-4.2.x on OS
X and Python: http://bugs.python.org/issue6957
But it also points out that XCode for 10.6 comes with GCC-4.0.1. The
default is 32-bit for GCC-4.0.1, unlike GCC-4.2.x, which on OS X defaults
to 643-bit. So... I'm now trying fresh 32 and 64-bit builds of Sage using
GCC-4.0.1. I'm doing this by changing my path to point to versions of gcc
and g++ that are the 4.0.1 versions, instead of trusting environment
variables, which are bound to fail. I'll report more here later.
Anyway, if this works, we'll be in good shape -- we could just revisit
4.2.x support later as components of Sage stabilize and people iron out
the bugs in the huge changes Apple may have made to C.
