[patch, fortran] PR20373 again ...

[Daniel Franke]

This sat long enough in my tree to actually attempt another try. It is 
essentially the same patch as submitted before, but this time all the parts 
together. To cite Jerry: a discovery patch ...

The last discovery was: the function types introduced for MIN/MAX broke a 
couple of tests, thus I removed them, all others may stay in place.

Bootstrapped and regtested on i686-pc-linux-gnu.
If there are no objections, I'll commit to trunk in 48 hours.
