[PATCH 12/16] Drop non-prototype C function header variants: 'break' test case

[Andreas Arnez <arnez at linux dot vnet dot ibm dot com>]

Remove old-style function headers from break.c and break1.c.  Adjust
break.exp accordingly; in particular eliminate references to the
removed locations "breakpoint 9, 13, and 16" from break.exp.

gdb/testsuite/ChangeLog:

	* gdb.base/break.c: Remove #ifdef PROTOTYPES, keep prototyped
	variant.
	* gdb.base/break1.c: Likewise.
	* gdb.base/break.exp: Drop references to removed code.
