QNX4-Patch

I have tried to build the 7.2 beta from cvs on QNX4. Found the following
problems :
MaxBackends not defined in semaphore test program.

*** tstsem.c Sun Nov 4 19:51:26 2001
--- tstsem.c.new Sun Nov 4 19:52:58 2001
***************
*** 26,31 ****
--- 26,33 ----
#define SEMMAX 16
#define OPSMAX 1

+ int MaxBackends = SEMMAX;
+
static int semid;

static void

Number of necessary semaphores in sem.c not consistent with
.../storage/lmgr/proc.c. IMHO, it would be better to change the macro
PROC_SEM_MAP_ENTRIES in proc.h to "((maxBackends+1)/PROC_NSEMS_PER_SET+1)"
instead. Otherwise the darwin port has a similar problem.

*** sem.c Sun Nov 4 19:53:22 2001
--- sem.c.new Sun Nov 4 19:52:46 2001
***************
*** 175,179 ****
return fd;
/* The size may only be set once. Ignore errors. */
! nsets = PROC_SEM_MAP_ENTRIES(MaxBackends);
sem_info_size = sizeof(struct sem_info) + (nsets - 1) *
sizeof(struct sem_set_info);
ltrunc(fd, sem_info_size, SEEK_SET);
