Does this have to be a separate static library, can we list vmstats.cc and
vmstats.h along with main.cc in the targets
'dart' and 'dart_no_snapshot'?

Do you see other executables wanting to link with this library?

[Tom Ball, 2013/02/14 23:45:16]

I added to them to the targets that include main.cc as you suggested.
