Thanks.

Well, it means HPUX_SOURCE & HIUX_SOURCE are only defined when the
-ansi switch is _not_ used.

Right.  However, that was a bug.

caddr_t is not an ANSI type.  Thus it is not available when you ask
for strict ANSI (-ansi).

If you want a strict ANSI environment use -ansi

If you want ANSI + the HPUX specific namespace pollution use 
-ansi -D_HPUX_SOURCE
