re PR c/35649 (Incorrect printf warning: expect double has float) 

2013-08-26  Joern Rennecke  <joern.rennecke@embecosm.com>

        c/35649
        * c-typeck.c (c_common_type): Prefer double_type_node over
        other REAL_TYPE types with the same precision.
        (convert_arguments): Likewise.

Amend patch as suggested:
From:  	"Joseph S. Myers" <joseph@codesourcery.com>
In convert_arguments I think you should be comparing TYPE_MAIN_VARIANT
(valtype) against double_type_node and long_double_type_node, rather than
just valtype.

This is PR c/35649 (so include that number in your ChangeLog entry and
close that bug as fixed).
