Argl... I've now checked it myself on a RedHat 5.2 box and HELL, Linux is such
brain-dead. semctl(2) is defined by Single Unix Specification (SUSv2) to be
int semctl(int semid, int semnum, int cmd, ...);
but RedHat 5.2 defined it incorrectly as:
extern int semctl __P ((int __semid, int __semnum, int __cmd,
union semun __arg));
That's unbelievable. Every time mod_ssl is broken on Linux it's because Linux
platforms are such broken theirself. Ok, ok, seems like we have to use IPC
semaphores only on glibc 2.1 platforms or we get more problems-of-the-week
with those old Linux beasts. Because RedHat 6.0 has the correct one in
sys/sem.h:
extern int semctl __P ((int __semid, int __semnum, int __cmd, ...));
Tz, I really love my FreeBSD if it comes to such things...
