Computed GO TO is on a list of a few noncontroversial things
with the property that they could be considered for removal
from the next standard (2001?) after the one coming up.  That does
not necessarily mean it will be removed from any compilers, however.
EQUIVALENCE and COMMON were on this list at one time, but no more.
The other stuff on the list is:

Arithmetic IF
Real and doubple precision DO variables
Do loops other than DO-CONTINUE (and of course, the new DO-END DO)
Alternate return
Branching to and END IF from outside the IF block
PAUSE statement
ASSIGN and assigned GO TO statements
Assigned format specifiers

There were better ways to do all these things already in Fortran 77.
