While this is definitely a compiler bug, it may be caused by a "buggy"
source (egcs/pgcc follows the current c++ standard much better than most
everything else). Also, the code uses a symbol (semun) not specified by any
standard.

BTW, the code is probably the cleanest c++ code I saw since a long time, so
after fixing the semun problem, the code compiled. I'd recommend upgrading
to pgcc-1.1, which is much more stable (and implements most of C++ ;)
