No, it's not intentional (I work for SGI). THe problem
is that gcc and IRIX cc use different structure passing
conventions on the stack. Normally this isn't a problem
as there are no system calls that take a structure rather
than a pointer..... except one :-). You guessed it, it's
that semop() call :-(. That's why to make Samba work with
sysV shared memory on IRIX you have to use IRIX cc. It
works fine if you tell it to use the shared memory code
that does mmap+fcntl locking.

Hope this helps,

Buying an operating system without source is like buying
a self-assembly Space Shuttle with no instructions.
