       We have reason to believe that even with a proper compiler the
7.0 release may not work with AIPS.  RedHat 7.1 does work.

      Why did you bother?  This is the version of the compiler that
warns about every variable in COMMON that  is not used in a routine
tha tincludes that COMMON.  Gbytes of erroneous warnings!

Yes it would.  Do follow our instructions and put it someplace other
than /usr/bin.  Your RedHat 7.0 was build with the 2.96 compiler and
it must stay in place to support your OS.  Install 2.95.3 someplace
else and point the AIPS compile procs at that place.  The web page has
all you need for this - I even installed 2.95.3 here following those
instuctions and it was suprisingly easy.
