   Are you sure the bug is in gcc 2.1, and not in groff for incorrectly using
   "delete ptrToArray" where the ARM requires "delete [] ptrToArray" ?

The current version of groff by default uses delete [] as the ARM
requires, although it can be configured to work with 2.0 compilers as
well.

   It
   appears that all your patch does is restore backward bug-compatibility.

The patch in fact disables a flawed backward compatibility feature in
gcc 2.1.  (I can't claim credit for the patch: it was posted to
bug-gcc by somebody else.)
