File which compiles fine under G77 (and ifort) fails under gfortran

[Arjen Markus]

Hello Patrick,

gfortran 4.6.0 gives the same (or at least very similar) errors, but
it is quite correct:
NAME is not defined as being a character string and therefore
assigning a character
string to it is illegal. The fact that g77 accepts this and that ifort
does not complain
(unless you give it an option like /warn:stderrors) does not really matter.

I have tried several options, like -std=legacy and -std=gnu, but the
compiler will not accept
this.

The best way, I guess, to make progress is to fix the errors, as they
_are_ errors.

Regards,

Arjen
