Synopsis: ia64 function pointer :

State-Changed-From-To: open->closed
State-Changed-By: janis
State-Changed-When: Thu Oct 10 17:15:43 2002
State-Changed-Why:
    This is not a GCC bug.  For GCC 2.96 (which is not an FSF
    release), the program works as expected if calloc is
    declared by including <stdlib.h>.  GCC 3.2, the current
    release, reports an error for an "invalid conversion
    from `int (*)(int, int)' to `const void*"; a function
    pointer on IA-64 is not a simple pointer as it is on some
    other architectures.

This code compiler correctly on Solaris/sparc, 
FreeBSD/i386, linux/i386.
