[LLVMdev] Color diagnostics

[Perry Hung]

Hi,

I'm using the official 3.6 release binaries for x64 Linux. When compiling
with warnings, I don't see any color diagnostics. Explicitly enabling
-fcolor-diagnostics works fine. I have TERM set to xterm-256color. Any idea
why?

For what it's worth, I tried compiling LLVM/clang from trunk and color
diagnostics work fine by default.

Upon further investigation, I saw that the official binaries were not
linked against libtinfo:

Is this a build issue or user error?
