Currently, the first scan does not count -b if its argument has no
dash. So the switches vector has no enough space for all switches and
is overflowed when the second scan tries to store the pointers.

	* gcc.c (process_command): Treat -b as normal switch if its argument
	has no dash.

Ok if regtest successful.
