Make FPU test #1 even more stressing.

Re-enable O3 again.
Revert Makefile.config not to compile in any tests.		  
90 6966 d 0 h vana /SPARTAN/trunk/ Set TS flag on system startup.
Some bugs in FPU context switching seem to persist.

On IA-32, this macro represents two doublewords that must be on the stack when switching to a new stack.
On MIPS, there is no need to fix sp when switching to a new stack.
On IA-64, this macro is used to allocate the 16-byte scratch area.
