   Brian,

	   Sorry about the lack of information -- from reading the code,
   I just assumed that the behavior I get was intentional.  I built
   bash-1.02 with exactly one change (prior to commenting out the line I
   mentioned), and that was just the MAINTAINER definition.  I'm running
   on a SUN 3/50 with OS 4.0.1.  (Note: I'm using gcc-1.35 with
   -traditional to compile bash.)

   I have the following environment (using bash as my default shell):

   nolinks=1

Hey Chuck, thanks for sending me that stuff.  Now I can see that when
`nolinks' is set the bug manifests itself.  Here is the complete patch,
which also makes a static variable static:
