AC_C_CONST and AC_C_INLINE with g++ 2.95

[Predrag Miocinovic]

Hi,

AC_C_CONST and AC_C_INLINE fail with gcc-2.95 if AC_LANG_CPLUSPLUS is
turned on. 
Const check seems to fail on following;
---------------------
/* Ultrix mips cc rejects this.  */
typedef int charset[2]; const charset x;
---------------------  with 
c++ -c -g -O2  conftest.C 1>&5
configure: In function `int main()':
configure:2346: uninitialized const `x'
----------------------

Inline fails with;
------------------
configure:2411: checking for inline
configure:2425: c++ -c -g -O2  conftest.C 1>&5
configure:2421: ANSI C++ forbids declaration `foo' with no type
configure: failed program was:
#line 2418 "configure"
#include "confdefs.h"

int main() {
} inline foo() {
; return 0; }
configure:2425: c++ -c -g -O2  conftest.C 1>&5
configure:2421: ANSI C++ forbids declaration `foo' with no type
configure: failed program was:
#line 2418 "configure"
#include "confdefs.h"

int main() {
} __inline__ foo() {
; return 0; }
configure:2425: c++ -c -g -O2  conftest.C 1>&5
configure:2421: ANSI C++ forbids declaration `foo' with no type
configure: failed program was:
#line 2418 "configure"
#include "confdefs.h"

int main() {
} __inline foo() {
; return 0; }
----------------------------

This is not critical since it's ok if AC_LANG_C is set before these tests.
