The HPUX compiler is especially tough on these messages. Many of
them are caused by inconsistencies in datatypes between platforms.
The return values were a cut and paste error that have no effect
on the program, since the function is void. Mixing void and void*
is potentially more serious - can you be specific?

I had a similar problem on DEC Unix, the compiler failed in cfservd.c. I have included a patch that makes cfservd.c compile (and run) with the native compiler on DEC Unix.

This patch also changes protoype.h - it comments CheckDFSSACE. Without that cfengine does not compile.
