I was referring to the gthr-posix.h change. It needs a
run of tools/gcc/mknative to have effect which I've only done
for i386 (mrg will do the rest).

No, that's the header. The check went in after the -5 branch.

This is fixed by the gthr-posix patch. You could ally it manually to
gthr-default.h for testing.

Don't know... If you get further with these patches pulled in,
we can consider pullups.
C language support is pretty good in 2.7 (as it as in 2.6 already);
for C++ it is advisable to use the wip snapshot because this is
developing rapidly.
