Since this, my vax-dec-linux-gnu cross-compiler is unusable. This is
while building uClibc:

  CC libc/misc/fnmatch/fnmatch.o
libc/misc/fnmatch/fnmatch.c: In function '__fnmatch':
libc/misc/fnmatch/fnmatch.c:222: internal compiler error: in condjump_equiv_p, at cfgcleanup.c:940
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
make: *** [libc/misc/fnmatch/fnmatch.o] Error 1

For what I think (and the author, see
http://gcc.gnu.org/ml/gcc-patches/2005-12/msg01258.html), it shouldn't
be p->x_start, but info->cur.x_start .
