Subject: Pass -fcolor-diagnostics when it is supported. This makes a difference when
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=18efed7adc79c1970f307bb5b015d199012ba872;p=oota-llvm.git

Pass -fcolor-diagnostics when it is supported. This makes a difference when
using cmake+ninja, since ninja buffers the compiler output.
