This is IMO a bug in the libc and/or kernel. I suppose the best
workaround is to write a configure rule that detects for the presence
of SYS_sysinfo and defines it, or something.
Alternatively you could redefine sysinfo in config.h to run a fake
version in compat.c that always returns the same numbers.
Anyway, I've reported the lack of an entrypoint or prototype for
sysinfo as a bug against Debian's libc packages and it doesn't seem to
have helped very much ...
If you send me some code for configure.in &c that deals with this
problem for you then I'll incorporate it into the next dpkg release.

Huh ? This really confuses me. Is this necessary for OSF/1
compatibility ? How am I to write code that works right on both
systems, if I refuse to use #ifdef ?
(Obviously I shouldn't need to use #ifdef to compile
architecture-independent code on different Linux systems !)
