Subject: Use std::string in break-catch-sig.c
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5809899dad253e2fefcb6f7ae57a6f43cfa4e3c5;p=binutils-gdb.git

Use std::string in break-catch-sig.c

This changes one spot in break-catch-sig.c to use std::string,
removing some cleanups.

2016-09-23  Tom Tromey  <tom@tromey.com>

	* break-catch-sig.c: Include <string>.
	(signal_catchpoint_print_one): Use std::string.
