CBound operator+= updated the minimum value or the maximum value, but
never both. (I think the operator+=(CVector3D) has always been buggy
(because it assumes min<max, which isn't true of empty bounds), and I
propagated the error to operator+=(CBound) ages ago.)
Added test cases, and fixed.
This was SVN commit r4244.
Premake: Changed to use PCH when compiling tests.
CxxTest: Got rid of /Wp64 warnings. Changed TS_ASSERT_STR_EQUALS to
print both strings on failure.
win_internal: Added the bits that CxxTest::Win32Gui needs (because
Win32Gui is now compiled with PCH and uses our sysdep headers).
Disabled test_cache_policies, because it took long enough for me to read
its name.
This was SVN commit r4237.
# Attempted to make compilation faster
by including as little as possible in some .h files, and moving it into
.cpp.
Fixed BaseTechCollection memory leak.
This was SVN commit r3992.
