You understand the basic concept. The binaries and libraries that make
up the compilation system need to be relative to each other. The compilation
system for example consists of drivers like "cc", which invokes components
acomp, iropt, ir2hf, ube, etc. Those binaries need to live in relative
locations to each other. Same with support libraries and other files.
Many of the binaries like those mentioned do not belong in /usr/bin, i.e.
on the user's path. So reorganizing this is a significant job for which we
do not have an estimate. This ARC case is about bundling the Sun C and C++
compilers in Nevada for all distributions of Solaris in a reasonable time
without reoganizing/redesigning those compilers. Such a reorganization of
the compiler so to place the binaries cc, CC, etc. in /usr/bin would be the
subject of another case.

If ARC members recommend we install the bundled compilers in /usr/lib/<mumble>
that is fine by us, it's just a name and a path. We chose /usr/compilers
as it was not clear to us that we want another WOS in /usr/lib.

If we do the reoganization of the compiler for binaries in /usr/bin with
support files in /usr/lib/<mumble>, then yes man pages go directly in
/usr/share/man.
