it not only sets the action yet can also set the global _OS. Currently when the function is used in
a test suite it should really be reset in a teardown. To make this transparent I have added the
caching of the _OS value set in C code in testfx and it is reset in 'test_setup' with the other
environment resets.
I had a quick look at the commits and can not see how or when this first caused a problem yet findlib
was failing on windows as previous premake.action.set('xcode3') had been made and therefore the
library it was looking for was 'm'.
io.eol is another potential setting which leaves a dirty environment for tests.
stopped 'runall' from running 'setup' and 'teardown' as tests which also stops the inflated test count that I noticed.
Added writing of runtime to io for test suites.
Added prj = premake.solution.getproject(sln, 1) to vs10 tests and removed the managed flag hack.
