[Wien] Fortran compiling errors to MAIN program

[Luc Fruchter]

I finally erased all files in the old Wienroot directory, installed the 
new version from it, using the old options for the compiler, and it works.

Apparently, only part of the options where copied when the SRC folders 
were replaced in the first procedure. Some others, related to the latest 
version of the Intel fortran compiler installed before trying the 
update, were not appropriate.

So, creating a new folder is indeed a good practice, at least to be able 
to reproduce all appropriate compiling options in the new installation.

Thanks
