F77 vs gfotran

[Levente Torok]

Hi All,

I ran into an error and while hunting for solution we have concluded that this 
bug exists for many years in the configure script.
Namely, if f77 is accessible (on ubuntu which is usually a link for an f2c 
(sic!) then configure generates a make file for using this.

However the leads to a bug as such:

===========

And the resolution is written by Jaroslav many times for on the list is :

./configure F77=gfortran

I believe this trap can be avoided.

(NB, the corresponding binary comes with the fort77 package on ubuntu)
