Subject: 	* fork-child.c (startup_inferior): Use target_wait and target_resume
X-Git-Tag: reverse-20080930-branchpoint~154
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3c35e65b000b530bf71bb4e283e237134d97c5ec;p=external%2Fbinutils.git

	* fork-child.c (startup_inferior): Use target_wait and target_resume
	directly instead of calling wait_for_inferior / resume.

	* infcmd.c (kill_if_already_running): Do not call no_shared_libraries
	or init_wait_for_inferior.
	(run_command_1): Call init_wait_for_inferior.
