Subject: r300: fix compiler bugs introduced with MRT changes.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f9d734c309ca044fc70dc79eafe32b12460d65c0;p=mesa.git

r300: fix compiler bugs introduced with MRT changes.

the first looks like a definite bug, the second I'm not so confident
of but it works.
