I'm afraid it took me so long to reply to this message that I've
lost the original.  I do remember that someone was complaining that
the Unix-PC 7300 C compiler did not work for arrays of pointers to functions.
The following small example demonstrates that (at least under rel 3.0)
the compiler does, in fact, work.  The C declaration for array of pointer
to function is not very obvious, so I suspect that there is some
chance that the original poster didn't get the declaration right.
In any case, the following does work!



char *one()	{return "one";}
char *two()	{return "two";}
char *three()	{return "three";}

/*
 * declare foo as array of pointer to function returning pointer to char
 */
char* (*foo[])() = { one, two, three };

main() {
    int i;
    for (i=0; i<3; ++i) {
	printf("%s\n", (*foo[i])());	/* prove that it works */
	}
    }
