pygco warnings

[salamb]

Below are warnings from building the pygco fork being used. These warnings seem to be from gco itself, though this repo has the latest version gco v3.0 as part of its repo.

GCoptimization.cpp:31:23: warning: 'GCO_CLOCKS_PER_SEC' initialized and declared 'extern' [enabled by default]
extern "C" gcoclock_t GCO_CLOCKS_PER_SEC = CLOCKS_PER_SEC;

@salamb I noticed this too. As much as I like to remove warnings for clean installs, we don't have time to get dragged down into fixing other people's code. You might be able to suppress these if you want to cleanup output during the build.
