Hi Phil,
We solved the problem in the following way under RedHat 6 with egcs1.1.2
#if defined(R__HPUX) || defined (R__ALPHA) || defined (R__SOLARIS) || \
defined(R__AIX) || defined(R__HIUX) || defined (R__MKLINUX) || \
__GLIBC_MINOR__ > 0
union semun {
int val; // value for SETVAL
struct semid_ds *buf; // buffer for IPC_STAT & IPC_SET
ushort *array; // array for GETALL & SETALL
};
#endif
#ifdef R__LINUX
# define SEM_A 0200 // alter permission
# define SEM_R 0400 // read permission
#endif
the test on GLIBC_MINOR is apparently doing the job.
