note to self: scanelf has zillions of warnings like this on this platform too

a lot of the pax-utils code has these warnings on different systems (not just scanmacho).  ive seen it on ia64/hppa/sparc linux systems.

i dont really think it's a problem.

in the meanwhile I've found out what the compiler is exactly trying to tell, and I think it's harmless too

looking into a different issue, i narrowed down this problem and fixed it.  just needed to use void* in important locations where the type really didnt matter.
