Use PCB_SAVEFPU_SIZE instead of a too-small size in savectx(). This
...
bug only affected FPU emulators. It might have caused bogus FPU states
in core dumps and in the child pcb after a fork. Emulated FPU states
in core dumps don't work for other reasons, and the child FPU state
is reinitialized by exec, so the problem might not have caused any
noticeable affects.
Cleaned up #includes.
