make bootstrap of gcc-4.6-20100501 snapshot on armv5tel-unknown-linux-gnueabi
fails in stage 2 as follows:
/home/mikpe/gcc-4.6-20100501/gcc/ira-color.c: In function 'assign_hard_reg':
/home/mikpe/gcc-4.6-20100501/gcc/ira-color.c:447:31: error: unused variable
'rclass' [-Werror=unused-variable]
/home/mikpe/gcc-4.6-20100501/gcc/ira-color.c:444:59: error: unused variable
'add_cost' [-Werror=unused-variable]
cc1: all warnings being treated as errors
I suspect r158911 (PR42895 patch) is responsible, I'll try reverting that one
now.

------- Comment #1 from mikpe at it dot uu dot se 2010-05-03 10:43 -------
Created an attachment (id=20545)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=20545&action=view)
suggested fix for PR43964
Confirmed r158911 to be the cause of this bootstrap failure. Attached patch
should fix it. So far tested with bootstrap on i686-linux and cross to arm.
I'm now running a full bootstrap (all languages except ada) on arm, expect 12
hours or so for it to complete.
