   Slack7.1/linux.2.4 compile error: storage size of `semun' isn't known
   
   Long Description
   Hi,
   I have a the following error compiling latest CVS of PostgreSQL:
   
   ipc.c: In function `IPCPrivateSemaphoreKill':
   ipc.c:246: storage size of `semun' isn't known
   ipc.c:246: warning: unused variable `semun'
   ipc.c: In function `IpcSemaphoreCreate':
   ipc.c:298: storage size of `semun' isn't known
   ipc.c:298: warning: unused variable `semun'
   ipc.c: In function `IpcSemaphoreKill':
   ipc.c:399: storage size of `semun' isn't known

   ipc.c: In function `IpcSemaphoreGetCount':
   ipc.c:502: storage size of `dummy' isn't known
   ipc.c:502: warning: unused variable `dummy'
   ipc.c: In function `IpcSemaphoreGetValue':
   ipc.c:513: storage size of `dummy' isn't known
   ipc.c:513: warning: unused variable `dummy'

   >From /usr/include/linux/sem.h:
   
    union semun {
      int val;                     /* value for SETVAL */
      struct semid_ds *buf;        /* buffer for IPC_STAT & IPC_SET */
      unsigned short *array;       /* array for GETALL & SETALL */
      struct seminfo *__buf;       /* buffer for IPC_INFO */
      void *__pad; 
    };
   
   
   Removing "void *__pad;" from the above makes the compile finish.
   
   
   Slackware 7.1
   linux-2.4.0-test9

   Odd.  Is configure defining HAVE_SYS_SEM_H in src/include/config.h?
   
   What was the last version you compiled successfully?

   That doesn't make much sense to me either ---- if the union declaration
   is broken, why no complaint when the include file is read?
