When using gcc-3.2.3 as bootstrap compiler, i386.c is miscompiled
with -O0 -fkeep-inline-functions (the latter option is what is new
in gcc 4.2 and why 4.1.x bootstrap didn't suffer from this, see

Now, gcc-3_2-branch is long time closed, so IMNSHO gcc-4.2+ should work around
this bug.
Agreed, we can simply say that GCC 3.2.x is not is a GCC version that supports
it. Would you mind writing the patch? I

Seems there were 2 separate bugs that are causing this miscompilation.
1) common_type (in contemporary gcc's common_pointer_type) will for the type
of the whole conditional expression use pointer to attribute const

2) is apparently PR11557, fixed in GCC 3.3.1+.
So, I'd say as workaround we should not use -fkeep-inline-functions for
GCC 3.3.1. Testing a patch for that.

This works for me on i686-linux-gnu. Can you first try compiling 3.4.x and
then trying compiling the mainline with that?
