The thing that was stopping me from commiting was that I'm now seeing
FAIL: gcc.dg/cpp/arith-3.c (test for bogus messages, line 257)
regression on i386 and x86-64 when starting bootstrap from 20050228
gcc-4_0-branch. But I have just verified that this is unrelated to my
macro.c fix (which doesn't change the code in any way on i386 even),
but it looks like libgcc.a(expr.o) is miscompiled at -O{2,3,s}.
So will need to do debugging once again for this, but will commit fix for
this PR first.
