# Built 32 bit, as the ThreadX and SMP suites are. This is not incidental for

# compatibility layer passes pointers through ULONG arguments, for instance the
# task argument and the timer identifier. A 64 bit build therefore truncates
# those pointers, which the compiler reports as -Wpointer-to-int-cast and which
# would crash the timer callback wrapper.
