[Bug c++/18886] New: attribute sentinel doesn't work with C++

["salinger at sun dot felk dot cvut dot cz" <gcc-bugzilla at gcc dot gnu dot org>]

NULL is expanded as __null in C++.
This is inconsistent with sentinel testing.
There should be one warning for both cases.

gcc version 4.0.0 20041128 (experimental)

$ gcc -Wall -c e.c

e.c: In function 'bar':
e.c:15: warning: missing sentinel in function call

$ g++ -Wall -c e.c
e.c: In function 'void bar()':
e.c:15: warning: missing sentinel in function call
e.c:16: warning: missing sentinel in function call

e,c:

#include <stddef.h> /* For NULL */

#ifdef __cplusplus
extern "C" {
#endif

extern int execl (const char *, const char *, ...);

#ifdef __cplusplus
}       /* C++ */
#endif

void bar(void)
{
execl ("/bin/ls", "-aFC");
execl ("/bin/ls", "-aFC", NULL);
}
