Hello world,

during testing, I noticed that parameters of the form
- mod(u1,u2) were rejected with an unknown type. The fix
is straightforward, but required an adjustment to another
test case.

Regression-tested.  OK for trunk?

gcc/fortran/ChangeLog:

	* resolve.cc (resolve_operator): Also handle BT_UNSIGNED.

gcc/testsuite/ChangeLog:

	* gfortran.dg/unsigned_38.f90: Add -pedantic and adjust error
	message.
	* gfortran.dg/unsigned_40.f90: New test.
