Summary: G++-4.6 Solaris incorrectly defines _RESTRICT_KYWD to
__restrict
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: edwinto...@gmail.com
Host: i386-pc-solaris2.10
Target: i386-pc-solaris2.10

G++ 4.6 shows this error, G++ 4.3.3 doesn't:
/usr/include/spawn.h:42:14: error: expected ',' or '...' before 'argv'
/usr/include/spawn.h:50:14: error: expected ',' or '...' before 'argv'
Solaris defines posix_spawn like this:
extern int posix_spawn(
pid_t *_RESTRICT_KYWD pid,
const char *_RESTRICT_KYWD path,
const posix_spawn_file_actions_t *file_actions,
const posix_spawnattr_t *_RESTRICT_KYWD attrp,
char *const argv[_RESTRICT_KYWD],
char *const envp[_RESTRICT_KYWD]);
With GCC 4.6 I see this in preprocessed file:
# 358
"/usr/local/lib/gcc/i386-pc-solaris2.10/4.6.0/include-fixed/sys/feature_tests.h"
3 4
...
#if (defined(__STDC__) && defined(_STDC_C99))
#ifdef __cplusplus
#define _RESTRICT_KYWD __restrict
#else
#define _RESTRICT_KYWD restrict
#endif
#else
#define _RESTRICT_KYWD
#endif
With 4.3.3 I see this:
#if (defined(__STDC__) && defined(_STDC_C99))
#define _RESTRICT_KYWD restrict
#else
#define _RESTRICT_KYWD
#endif
The system header is:
/usr/include/sys/feature_tests.h:
#if (defined(__STDC__) && defined(_STDC_C99))
#define _RESTRICT_KYWD restrict
#else
#define _RESTRICT_KYWD
#endif
Don't know where the #define to __restrict on __cplusplus comes from, but it is
wrong.
GCC 4.6 is:
Using built-in specs.
