* Add FIXME in multiple_ranges_test.cc * Improve handling of large bounds in AddRange. Due to breaking the loop too early, AddRange would miss a final multplier of 'mult' that was within the numeric range of T. * Enable negative values for Range argument Fixes #762. * Try to fix build of benchmark_gtest * Try some more to fix build * Attempt to fix format macros * Attempt to resolve format errors for mingw32 * Review feedback Put unit tests in benchmark::internal namespace Fix error reporting in multiple_ranges_test.cc
