It breaks things how?
Because on x86, the cut-off is gcc4 vs pre-4. See arch/x86/Makefile:
KBUILD_CFLAGS += $(shell if [ $(call cc-version) -lt 0400 ] ; then \
echo $(call cc-option,-fno-unit-at-a-time); fi ;)
and it's a bit distressing that these compiler flags are set two different
ways (in fact, I was already bothered by the fact that UML sets it totally
independently of x86 in the first place).
So what is the UML failure behaviour with gcc-4.1.2?
