PATCH: Fix bootstrap on 32bit host

PATCH: Fix bootstrap on 32bit host

[H.J. Lu]

Hi,

On Linux/ia32, I got

cc1: warnings being treated as errors
../../src-trunk/gcc/tree-parloops.c: In function 'parallelize_loops':
../../src-trunk/gcc/tree-parloops.c:1911:51: error: comparison between
signed and unsigned integer expressions
make[6]: *** [tree-parloops.o] Error 1

I am checking this patch as an obvious fix.

H.J.
