In the bug they mention a workaround, you could try it...

That's exactly the same, yes. The workaround seems to do, though funnily now I have to rename main to __main (since the linker complains otherwise) and manually link against the CRT... on the positive side, executables are considerably smaller than they used to be, just by flipping the magic switch.

Yeah well, that would be just constexpr, really. It's the only truly interesting thing in 4.6 (from my perspective) that 4.5 did not already support.

Freem:
Sorry for the off topic question, but, what is LTO?

oBFusCATed:
Link time optimization.

I find also very interesting in 4.6 :
- nullptr
- range based for

:-)

byuu:
When I compile with -fopenmp, I receive the following:

g++: error: libgomp.spec: No such file or directory

It worked with TDM/GCC 4.4, but not 4.5 or 4.6. Is there any way I can fix this?
