Including gtest.h fails on OS X about diagnostics HOT 8 CLOSED

This looks more like a bug in gtest. That said, it's also potentially fixable here by including a newer version of gtest.

Is this reported against gtest and fixed in a newer version?

gtest-1.7.0 works on my environment (yotemite, llvm 3.5)

from diagnostics.

I have gtest 1.7.0 installed with brew but diagnostic_aggregator seems to be using its own gtest (1.6.0). At least that is what looks like from the error I get:

ros_catkin_ws/src/diagnostics/diagnostic_aggregator/gtest-1.6.0/include/gtest/gtest.h:1561:13: fatal error: 'tr1/tuple'
      file not found
#   include <tr1/tuple>  // NOLINT
            ^

Could you try this PR?

@FBaralli as per the recommended gtest practice, diagnostics includes and builds its own copy of gtest. It doesn't use the system version.

I've upgraded gtest to 1.7.0 in the hydro-devel branch. Please test and verify that it works before I do a release.
