Hi!

I encountered a MT related bug while building theide. In speed mode, with flags GUI, NOGTK and MT flags, linking fails with

undefined reference to 'Upp::ReadMemoryBarrier()'

.
With optimal mode, there is no problem. Also adding SSE2 removes the problem.

The function ReadMemoryBarrier() is defined in Core/MT.cpp, on line 266 as inlined. As far as I can tell that is the problem. If I remove the inline keyword, everything compiles correctly.

OK, 'inline' removed. Thanks.

The question is whether SSE2 should not be default... (and NOSSE2 exist instead).

How does it run U++?
