Messages about spawning a process

[Raymond Toy]

I noticed this when running the Maxima testsuite with gcl 2.7.1:
|***** Spawning process echo |

There are also message about spawning gnuplot. This can be easily 
duplicated by doing:

|system("echo abc"); ***** Spawning process echo abc |

Are these really necessary? Can they be disabled? The other lisps I 
tried (cmucl, ccl64) with maxima just print “abc”, which is what I think 
people expect.
