I have found the following simple patch useful for
building OpenSSH 3.8p1 on my Tru64 V4.0G boxes with Heimdal 0.6.
The problem is that Heimdal defines the intXX_t types in <krb5-types.h>
and these then clash with OpenSSH's own definitions in
"defines.h".
The patch should be harmless on other platforms (at least if they are
sane and don't define __BIT_TYPES_DEFINED__ without also declaring the
corresponding datatypes).
