[Bug 1324901] [NEW] Enable colors in GCC 4.9

[Manuel López-Ibáñez]

Public bug reported:

GCC 4.9 supports colored diagnostics. Enabling them requires either
using -fdiagnostics-color=auto or defining GCC_COLORS.

Ubuntu could enable colors in gcc by default just for those users who
already use colors for ls/grep by patching the file /etc/skel/.bashrc
