	* gcc-interface/utils.c (handle_nonnull_attribute): Quote attribute
	name.

gcc/c/ChangeLog:

	* c-typeck.c (build_binary_op): Hyphenate floating-point.

gcc/testsuite/ChangeLog:

	* gcc.dg/Wfloat-equal-1.c: Adjust text of expected diagnostic.
	* gcc.dg/misc-column.c: Ditto.

gcc/ChangeLog:

	* tree-pretty-print.h: Remove unnecessary punctuation characters
	from a diagnostic.
	* tree-ssa.c (release_defs_bitset): Correct preprocessor conditional.
