Oh, sorry, I missed the attachments in the previous email. Here we have the 
likely problem: you're running GCC 4.1. That's not supported, it's too old. At 
least 4.2 is necessary, and that's for Mac OS X's sake.

I highly recommend you upgrade, to at least 4.4. I do notice that you're 
running RHEL 5 and, given the kernel's compilation date, you're still getting 
updates. In turn, I must conclude that RH is not giving updates on the 
compiler. That's unfortunate.

Still, can you try changing the line in question to be:

static const TestData inNativeEndian = { Q_UINT64_C(0x0123456789abcdef), 
0x00c0ffee, 0xcafe, 0xcf, '\0' };

If that works, we should apply the fix. It's the right thing to do anyway.

If it doesn't, I'm not sure we should do anything, actually. This is a unit 
test and I don't expect anyone to be concerned about running the tests with 
GCC 4.1. Aside from miscompilation issues, the result of the tests is the same 
no matter what compiler you use.
