Are those times for the full build process or just running the tests?

And do I read the table correctly in that the second of the repeated row labels is for g++ on linux and gcc on non-linux?

A short extract is below showing two rows for the first two columns, representing "HP-UX - 11.11" and "HP-UX - 11.23". These are non-linux so am I correct that this means 106.3 for cc and 147.4 for gcc on those platforms? Although then I'm wondering what the values after the forward slash are.

-Duse64bitall     106.3 /  97.2      59.6 /  66.3     
-Duse64bitall     147.4 /            79.7 / 108.4

Edit: But now I see the labels at the bottom of the table, so the repeated labels are for where -DDEBUGGING is set, and the forward slash separates the compilers. That answers the second part of my question.
