Compilation with GFortran - X descriptor requires leading space count

[MartinBeseda]

Hello,
when I'm trying to build Duo with gfortran v 8.2.0, I'm getting a following error:

martin@martin-pc:~/Duo$ make -f MAKEFILES/makefile_gfortran 
gfortran -c diatom.f90 -fbounds-check -std=f2003  -O0

make: *** [MAKEFILES/makefile_gfortran:36: diatom.o] Error 1

Is there a possibility of some easy fix?

I have fixed these gfortran-related issues. Can you please try the MOLPRO brunch?
https://github.com/Trovemaster/Duo/tree/MOLPRO
This is my main development version which I am planning to make default eventually.

Cheers,
Sergey
