PATCH: PR boostrap/44421: [4.6 Regression] Failed to bootstrap

[H.J. Lu]

Hi,

This patch:

http://gcc.gnu.org/ml/gcc-patches/2010-06/msg00298.html

breaks bootstrap on targets which define EH_USES:

ia64/ia64.h:#define EH_USES(REGNO) ia64_eh_uses (REGNO)
m32c/m32c.h:#define EH_USES(REGNO) 0   /* FIXME */
mips/mips.h:#define EH_USES(N) mips_eh_uses (N)

I checked in this patch as an obvious fix.
