pnetcdf 0.8.8 release

[Rob Ross]

Hello,

I've put up version 0.8.8.  Major changes include a big cleanup in the
test directory and fixes to the makefiles to address issues on the NEC and
AIX platforms.  Hopefully make; make install; make tests will just work
now.  A configure script is included, so you don't need to run autoconf.

I did not get to Tyce's fixes for the Fortran test yet.  This might end up 
waiting until RobL and Jianwei work on this.  Probably matters less now 
that John has some things working, but I still want to get it fixed.

I haven't tried an out-of-tree build lately, so I don't know if this is 
working.  I will check that out soon and make sure it's still ok.

Rene -- any suggestions on getting the cross-compilation to work on your 
system?  I've never tried to deal with this before.

I've also added notes for building on the Jazz linux cluster here using 
the Intel compiler suite.  This looks good so far.  Will need more testing 
though to make sure that everything is ok.  One thing to note is that I 
get a slew of warnings out of the Intel compilers that look like issues 
with the things I *added* to get rid of the warnings under the other 
platforms!  Ack!

Thanks all,

Rob
