Subject: Change get_inferior_args to return const char *
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cbaaa0cafcac0630c6f07f81663a1b10a4e197a0;p=binutils-gdb.git

Change get_inferior_args to return const char *

I noticed that get_inferior_args should return const char *, because
it is just returning a reference to something owned by the inferior.

I'm checking this in.
