gdb/testsuite/

	Fix spurious false FAILs.
	* gdb.base/structs.c (chartest): New.
	(main): Fill-in chartest.
	* gdb.base/structs.exp (anychar_re, first): New.
	(start_structs_test): Import global anychar_re and first.
	New gdb_test call "set print elements 300; ${testfile}"
	(start_structs_test <$first>): New block.
	(any): Import global anychar_re.  New variable ac.  Use ${ac}.
