Code is missing to correctly register a non-VM thread with Boehm GC. This is needed to
handle JNI_AttachThread.

I prepared a patch that worked with BoehmGC <7. A port is neccessary to let it work with
7.1.

fix for attachthread problem with boehm gc 6.x

The attached patch is the solution that worked for me when Cacao used the built-in Boehm
GC 6. It needs some porting to get it working with Boehm 7.X.

Boehm 7 introduces the function:
int GC_register_my_thread(struct GC_stack_base *sb);

This should be used instead of

GC_thr_init_foreign()

which I wrote in the attached patch.

I'll fix it for the 0.99 release.
