[daip] GNU gcc 3.0.4

[Eric Greisen]

I have tested the 3.0.4 compiler on AIPS.  There seems to be an
improvement in real times, but the cpu times remain the same - about
15% greater than with 2.95.3.  The compilation bugs remain.  A
summary: 


Linux  1.3 GHz 512 Mbyte                   2/05/02

   3.0.4  Miscompiles COMB, messing up on an array (7,4) in COMMON.
          When it is accessed, other bits of memory get changed

          The host name becomes !!imate apparently right off when AIPS
          or other stand-alone programs are started.

   With COMB compiled NOOPT, the DDTs and Y2Ks ran.

   2.95.3   70 - 75 sec    and  706 - 711 sec   Cpu= 10.32, 10.28, 10.217

   3.0.2    91 - 93        and  802             Cpu= 11.84

   3.0.3    92 - 93        and  814 - 829.      Cpu= 11.86, 11.77

   3.0.4    83 - 85, 91    and  741, 739, 736   Cpu= 11.68, 11.70, 11.77
