Re: 64bit HPUX problems

[ross . alexander]

Albert,

I don't think we can't really rely on cflags because because the user could
be using gcc, in which
case we would have to look for __LP64__ (I think).  I think it might be
easier to check
$host_cpu for hppa2.0w.  However, a user wanting to build for 32bit would
then have
to set the build to hppa2.0n-hp-hpux*.

Why don't you look at CFLAGS for +DD64? We do something similar for
AIX by examining LDFLAGS for -brtl.
