Building glib-2.28.2 on OS X 10.6, forcing a 64-bit-only build, 'make check' fails with:

In the past, there have been occasional collation problems on OS X due to case-(in)sensitivity or system-related encoding games. I'm not sure how to diagnose the particular result here, but can certainly try any ideas to get more info about what's going on. I am not setting any particular LC or other locale variables in my shell.
