release dates for 1.37 to 1.42, and prior to 1.17

[DJ Delorie]

I've just updated the releases page ( http://gcc.gnu.org/releases.html )
with historical information I dug up from djgpp's old gcc archives.
However, I'm still missing dates for some releases.  I only found
1.17 through 1.36, and 2.0 forward.

I'm missing 1.37 threough 1.42 (or were there more 1.x?) and prior to
1.17

If anyone has information about these releases (changelogs, news, mail
announcements) please email them to me.

Thanks!
DJ
