We don't really care which build of the GDB library we use; the problem is if we use the 2012 toolset then we have to use the 2012 GDB library, which means our software won't run on XP, unless the library is (someday) rebuilt with the 2012_XP toolset. That seems easy enough to do, hence my inquiry. Since Visual Studio 2014 is slated for release I'd rather at least be using the 2012 toolset, rather than the 2010.
