I have used following code:

set terminal postscript eps 'Times-Roman' 24
set output 'illu7test-with-pattern.eps'
plot sin(x)
set output

With the pattern code, Illustrator 7 cannot load the file. When
surrouding the code by

  false {
  ...
  } if

or using it for definition of a new function

  /NewPatternFill {
  ...
  } def

the file can be loaded. May be the pattern fill code can test if
NewPatternFill has already been used (by setting a boolean) and then call
it once if needed. Then, eps files that do not use patterns can be loaded
while the ones the use them fail to be loaded by Illustrator 7. The
Computer that runs Illustrator 11 is off, already. But Illustrator 11 has
been able to load all eps files until now.
