I confirm the issue and the fix with latest -CURRENT (gcc 4.2 and symbol
versioning). I have less RAM and swap than Michiel, and 800MB of total
memory are not enough to build xf86scanpci.c with default CFLAGS (and
even with less aggressive -O). I had to remove completely the
optimization flag, but only for this single source file, all the rest
can be compiled with -O2.
