Comment(by jhpalmieri):
Replying to [comment:33 leif]:
> Well, the status quo is (or was) to '''do nothing on any operating
system other than MacOS X or SunOS/Solaris'''. (I.e., `SAGE64` '''was'''
effectively ignored w.r.t. `sage-env` / `sage-check-64`. The assumption in
`spkg-install`s is that a non-empty `SAGE64` ''implies'' MacOS X or SunOS;
we previously had tests like `if [ "$SAGE64" = yes -a "$UNAME" = Darwin
]`, until Dave began to port to Solaris, first ''adding'' a test for
SunOS, then dropping the distinction on `$UNAME`, which as a side-effect
then slightly changed the meaning or possible interpretations of the
`spkg-install` files regarded in isolation. Of course removing the OS
dependency '''there''' makes sense, as long as the overall meaning is
kept.)

incomplete logic).
"Quite different" is not accurate. The only functional difference was that
previously on non OS X or Solaris systems, if SAGE64=yes, then the file
sage-64.txt would not be created or read. Now it is. Some extra messages
are also printed. (Yes, previously sage-check-64 ignored SAGE64 on Linux
boxes, but many spkg-install files do not.)
