Now in earnest here is the situation: There is NO trustworthy version
of an official GPL 2.0 text: the FSF official texts are all fubar (if
only in small and subtle ways). The FSF texts should be authoritative,
but then which one? they published more GPL 2.0 versions than most. So
we would be hard pressed to blame SPDX or the OSI for having their own
minor variant.

Then in digging further, I found the ONE true original GPL with a file
time stamp on June 2 1991, 01:50 (AM?, PM? unknown time zone?)  ! in
an old GCC archive.

For the posterity and everyone's enjoyment I have built a git history
of GPL 2.0 Mark1 to Mark6

See https://github.com/pombredanne/gpl-history/commits/master/COPYING

Each commit message has the link to the original archive.org page or
archive download.

For simplified diffs, the allvers/ dir contains all the versions of the texts.

Acks and reviews are welcomed, but not really.

I also added a shorter history of the Linux COPYING text. The first
version in Linus's git tree is based on the very fine and well tuned
GPL 2 Mark4, the first fully Y2K compliant version of the GPL 2, as
you can see from the diffs with the former Mark3: that was dangerously
stuck in the last century.

The current version in is based on a rare GPL 2.0 Mark5.1 aka
"Franklin St",  that I do not have in my history yet and spells
"Franklin St." rather than "Franklin Street."
Therefore there is likely another GPL 2.0 version between Mark4 and
Mark5 that I have yet to find and may not have been caught by the
archive.org spiders. Here help and patches welcomed: this is likely
an important missing link.

Linus:
I am rather sad to see that you never adopted the GPL 2.0 Mark6 ;)
aka. the  "final frontier" or "graveyard" release that came after the
GPL 3 launch and when the GPL 2.0 was made an "old" license: this
latest version is the finest ever published and I am sure we are all
missing out something worthy!

I look forward to the future publication of Mark7 and all the fine GPL
2.0 versions to come that we should all long for.
