Subject: [PATCH] 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.
