[PATCH] PR fortran/84511 -- Fix C_LOC in a transfer statement

[Steve Kargl]

All,

The attached patch handles C_LOC in a transfer statement
such as "print *, c_loc(xxx)".  The bug report contains
two files that must be compiled separately to exhibit 
the bug.  I have no idea how to write a testcase for this
situation.  If someone can write a testcase, I'm fine
with that.  If someone can tell me how to write a testcase,
I'm fine with that, too. 

Regression tested on x86_64-*-freebsd.  OK to commit?

	PR fortran/84511
	* trans-io.c (transfer_expr): Deal with C_LOC in transfer statement.
