An Algol 68 front end for GCC

While some people are focused on new and trendy languages, José Marchesi
has, instead, gifted the world with a GCC front
end for the Algol 68 language.

This WIP is a GCC front-end for Algol 68, the fascinating,
generally poorly understood and often vilified programming
language. It is common knowledge that Algol 68 was well ahead of
its time back when it was introduced, and anyone who knows the
language well will suspect this probably still holds true today,
but more than fifty years after the publication of the Revised
Report the world may finally be ready for it, or perhaps not, we
shall see.

For those who see Algol 68 as too new, there was also a
COBOL front end posted in December.
