It seems to be a bug in gcc 3.1.
I filed a bug report to them.
It generates wrong code when compiling NSSwapI* in NSByteOrder.h with -O2
Some possible work-arounds:
- compile without -O2
- add a call to a bogus function (one that does nothing) as first thing in the
NSSwapI* functions.
- put those functions in a .c file, to compile as real functions (not inlined).
