Looks good!
Using 1.4.4, compiled the 09/27 patch on an u3 system and ran on
u4 system. Compiled the 09/28 patch on the u4 system (source
in AFS) using the cache manager from the 09/27 patch.
Installed the 09/28 cache manager on the u4 and it too is running.
(still to test is running the u4 built version on a u3, and building
on 5.8 and 5.9 just to make sure they still run.)
The u3 system is: 5.10 Generic_125100-10 sun4u sparc SUNW,A70
The u4 system is: 5.10 Generic_120011-14 sun4u sparc SUNW,Sun-Fire-280R
P.S.
Built the aklog using the u4 provided /usr/include/kerberosv5/krb5.h
and it runs on both the u3 and u4 systems.
To build aklog required this patch:
http://www.openafs.org/dl/openafs/1.4.4/sun4x_510/aklog-solaris10-krb5.diff
(This is in the CVS but not part of 1.4.4.)
The build was done using:
KRB5CFLAGS="-I/usr/include/kerberosv5"
KRB5LIBS="/usr/lib/gss/mech_krb5.so -R/usr/lib/gss"
export KRB5CFLAGS
export KRB5LIBS
./configure --enable-transarc-paths \
--with-krb5=yes \
--enable-namei-fileserver \
--enable-largefile-fileserver \
--host=sparc-sun-solaris2.10
