Subject: declare getpass in analyzer/sensitive-1.c test
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=088e46b8d4d81e429f78ca75b47a179f489be16d;p=gcc.git

declare getpass in analyzer/sensitive-1.c test

The getpass function is not available on all systems; and not
necessarily declared in unistd.h, as expected by the sensitive-1
analyzer test.

Since this is a compile-only test, it doesn't really matter if the
function is defined in the system libraries.  All we need is a
declaration, to avoid warnings from calling an undeclared function.
This patch adds the declaration, in a way that is most unlikely to
conflict with any existing declaration.
