	Do you have ANSI-C compiler ?
	Is your system running in 64-bit mode ?

	This smells like non-ansi treatment of 64-bit wide
	pointers where default type size is 32 bits.
	(Alphas have this same problem if compilation is not
	 done in ANSI-C mode.)

	If that turns out to be the case, I propably need to
	have some hands-on experience with your host to tune
	the autoconfig to understand AIX 4.1.4.0 better.

	Try setting breakpoint at  sp_install(),  and see what parameters
	it gets when it is called.  (step a few "next"s, and print the
	parameters - especially the q, and then "continue")
