Universal binary t-get_d test failure

Hello! When building a universal binary of gmp 4.2.2, the t-get_d  
test fails:

Looks like an endian issue. I know you don't like Apple's gcc, but  
all the tests pass when building just for the local architecture  
(i.e. not building a universal binary). I confirmed this fact on Mac  
OS X 10.4.11 with Xcode 2.4.1 and on Mac OS X 10.5.3 with Xcode 3.0,  
both on a Core 2 Duo Intel MacBook Pro.

Is this something that can be fixed in gmp, or should one not attempt  
to build a universal binary of gmp?

The way I'm building gmp universal is through the MacPorts gmp port  
with the +universal variant, which does it by configuring this way  
(on 10.4.11):
