Hey john!

 jf> I believe yes, a c compiler is part of the unix specification.

I am not sure about 'specification' but am certain that c and unix since day
one have been welded together, sort of like the wave-particle duality in
physics.

 jf> But linux by itself isnt unix, its unix when you add on a lot of
 jf> gnu tools.

gcc and glibc being the prime suspects in the above scheme.  Up to this point
in time they have been on my must-have list and after doing a bit of research
on clang I am not convinced it will ever take gcc's place on any of the boxes I
have the pleasure working with.  I believe I know why the bsd people find it
attractive and have no issues with them as long as I stay away from joining
them in their pursuit of that particular cause, if indeed I do have a handle on
the cause.

 jf> dont open google

Yeah they really have gone downhill and look to be getting worse as time goes
on.

 jf> dont read an orielly book

I had a perl manual that wasn't too bad although the book itself fell apart at
the seams.  Shoddily bound for sure.

 jf> stick to man or info

I prefer info to man.  Also the --help switch to many applications can be
extremely helpful in a pinch.

Life is good,
Maurice
