Subtly different from what I wrote.. the version I wrote did this ..
+KBUILD_EXTRA_WARNINGS += $(call cc-option, -Wunused-but-set-variable)
I just tested with the gcc 4.4.5 on master.kernel.org, with a tip of Linus'
tree with my original diff, and it didn't complain at all.
What does gcc -v say ?
gcc version 4.4.5 20101112 (Red Hat 4.4.5-2) (GCC) seems to be fine.
(note the above hunk isn't relevant unless using W=1 builds anyway,
so I'm at a loss as to what broke it..)
