Does anyone know why the %ld formats are not recognized as valid?

Yes, for the x86_64-pc-mingw32 the %ld printing exists, but it is for long, not
for long long. For this target long is 32-bit scalar, so the printf formatters
are wrong.
in gthr-win32.h there seems to be a more serious bug. The cast of an integer
with less size to a pointer can be seriously wrong.

I don't think it's an issue: the type objc_thread_t, which is used as a thread
identifier, it declared as (void *), so it's larger than the integer types that
are cast into it (which are DWORD). It's inelegant, but I think it cannot cause
bugs.
I suggest silencing the warning that way (in both libobjc/thr-win32.c and
gcc/thr-win32.c):

I agree, that this patch does not break things and the build for this target
gets more silent.

Kai, can you apply FX's fix?

Ok I fixed at revision 151077 the issues about gthr-win32.h, the objective-c
library warnings aren't fixed by this.
