cat $CC and $CPP?  I'm not allowed to do that, except as root or bin...
-rwx--x--x   1 bin      bin        62140 Aug 21  1989 /bin/cc
-rwx--x--x   1 bin      bin        39062 Aug 21  1989 /lib/cpp

Which brings up what I consider to be a strange point:  Why is it that most
*NIX vendors ship systems with all the files in /bin and /usr/bin world-
readable?  It seems to me that they only need to be world-executable...

And I could imagine someone learning some unpleasant things with a dis-
assembler and some program that does important things... (/bin/passwd,
maybe?  naah...)

OBTW:  SCO ships things with 711 permissions, unless it's a shell script.
Interesting, since they seem to be more concerned about security than most...
