- solaris2.x renamed to solaris. There are recent changes to this file
but the "2.x" is misleading since the changes are applied to all
versions.
- Removed support for OSF 4.x/5.x (Digital and Tru64 Unix). We no
longer have the config files for these.
Tested on: jam (autogen.sh only)
emu (Solaris 11)
