although I have got these options in my kernel configuration file ...

options         SYSVMSG         # System V-like message queues
options         SYSVSEM         # System V-like semaphores
options         SYSVSHM         # System V-like memory sharing

... a program dies with "ENOSYS" on calls to "shmat()":

 29041 maudio   CALL  #228 (unimplemented shmat)(0x10009,0,0)
 29041 maudio   RET   #228 (unimplemented shmat) 1140854784/0x44001000
 29041 maudio   CALL  exit(0x1)

Has anybody got an explanation for this?

	Thanks in advance
