Again: NT4 sp3  cygwinb19.1  using egcs1.0.2 and gas980303 X11R6.3 from
da Silva for b19/egcs1.0.2

Plotutils 2.0 compiles with minor difficulties, crashes when plotting to
X.  Appears to have worked with b18 and coolview.

Using gdb, I have isolated the problem to a call to fork (specifically
x_closepl.c line 41)

  forkval = fork();
<------ causes SIGINT and/or other errors
  if ((int)forkval > 0)  /* parent */

the return from fork (the only reference to fork in the whole code) is a
value of the order of 1111, with a SIGINT or other type of error.

Is this a problem with fork?  If so, is there a work-around?  How does
this effect the operation of other codes?  It appears related to some
other fork-related problems being reported.
