The recent warning patches broke the libssp build on Solaris:
/vol/gcc/src/hg/master/local/libssp/gets-chk.c: In function '__gets_chk':
/vol/gcc/src/hg/master/local/libssp/gets-chk.c:67:12: error: implicit
declaration of function 'gets'; did you mean 'getw'?
[-Wimplicit-function-declaration]
67 | return gets (s);
| ^~~~
| getw
/vol/gcc/src/hg/master/local/libssp/gets-chk.c:67:12: error: returning
'int' from a function with return type 'char *' makes pointer from integer
without a cast [-Wint-conversion]
67 | return gets (s);
| ^~~~~~~~
/vol/gcc/src/hg/master/local/libssp/gets-chk.c:74:12: error: returning
'int' from a function with return type 'char *' makes pointer from integer
without a cast [-Wint-conversion]
74 | return gets (s);
| ^~~~~~~~
The guard around the gets declaration in gets-chk.c is
|| (defined __cplusplus && __cplusplus <= 201103L))
extern char *gets (char *);
where __USE_ISOC11 is glibc-only, while Solaris <iso/stdio_iso.h> declares
gets like
extern char *gets(char *) __ATTR_DEPRECATED;
Instead of using a target-specific macro, this patch just uses the
canonical autoconf test.
Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11,
x86_64-pc-linux-gnu, x86_64-apple-darwin23.3.0, and amd64-freebsd14.0.

libssp:
* configure.ac (AC_CHECK_DECLS): Check for gets.
* configure, config.h.in: Regenerate.
* gets-chk.c (gets): Guard declaration with !HAVE_DECL_GETS.
