		# headers being used.  It does not suffice to have the correct
		# "-I${SYSROOT}/usr/include" in the CFLAGS variable in make.conf as the
		# gcc include directory search order will always look in those
		# directories last.
		# 2. Use hostpython and header files from ${SYSROOT} for regen
		# 3. Makefile uses hostpython for compileall
