This turns on garbage collection for g77.  It passes the g77

Unfortunately, I am in no position to judge the work from the
patch alone.  I'll try to build with it on my m68k-next-nextstep3
system.

However, one small nit:

You'd probably meant to update this header ...

PS: Because it seems de rigeur to quote Nixon on these mailing
    lists lately, here's my contribution:

"Now for the first hundred days, Richard wandered in the wilderness
of Washington, from the deserts of dissent to the mountains of
moratorium - seeking the signs of the times.

But then the Pharizees came onto him, and certain of the Scribes,
and the young man, who studied not-for-war, for they had read the
gospel according to John the Leftist, and they grew hair, and wore
coats of many colors, so that even Salomon was not araved like one
of these.

And the Pharizees asked: `What of the inflation ?'
And Richard replied: `Glad am I that thou hast asked that question.'
And the Scribes asked: `What of integration ?'
And Richard replied: `I would make myself perfectly clear on this
point.'
And the young men cried: `When shall we have peace ?'
And Richard replied: `Let me say this - and let us make no mistake
about it.'
