Wrong, this rather likely. It is a classical BSD (bcopy) vs. SYSV
(memset) portability issue, because real SYSV systems do not have
bcopy and friends at all (I don't know any details about AIX, so I
can't comment in this specific case).
FYI: From linux's bcopy man-page:
CONFORMING TO
4.3BSD. This function is deprecated -- use memset in new
programs.
The bcopy in X11/Xfuncs.h is just a hack X11 applies to work around
this issue. Portable programs have to apply similar portability
checks if they are supposed to be compileable on old SYSV or BSD
systems. As mem* functions are available on most contemporary OSes I
would recommend to use mem* family functions (ISO-standard) only and
to map b* functions etc. to mem* functions on OSes which don't
provide them.
