Did little digging, TIL that the gfortran binary is part of GCC.. as
gfortran binary. So I do have fortran, but I never use it.

Also found out why fortran tests were failing for me.. by default the gcc
version on my system (RHEL 6.6) is 4.4.7. Using GCC 6.1.0 passes the full
"make test" on emacs 25.2.

For example, this is one of the ob-fortran examples that was failing:

* matrix
  :PROPERTIES:
  :ID:       3f73ab19-d25a-428d-8c26-e8c6aa933976
  :END:
Real matrix as input
#+name: fortran-input-matrix1
| 0.0 | 42.0 |
| 0.0 |  0.0 |
| 0.0 |  0.0 |

#+name: fortran-input-matrix2
| 0.0 | 0.0 | 0.0 |
| 0.0 | 0.0 | 42.0 |

#+begin_src fortran :var s=fortran-input-matrix1 :results silent
write (*, '(i2)'), nint(s(1,2))
#+end_src

#+begin_src fortran :var s=fortran-input-matrix2 :results silent
write (*, '(i2)'), nint(s(2,3))
#+end_src

Doing C-c C-c on the first source block gives this error with gcc 4.4.7:

/tmp/babel-6872M6V/fortran-src-6872rcR.F90:4.27:

real, parameter :: s(3,2) = transpose( reshape( (/(/0.0, 42.0/), (/0.0,
0.0/),
                           1
Error: transformational intrinsic 'transpose' at (1) is not permitted in an
initialization expression
/bin/sh: /tmp/babel-6872M6V/fortran-bin-68724mX: Permission denied

That expression is apparently legal in newer fortran, is my guess.

Thanks. I confirm that make test on org master passes with emacs 25.2.

Will do.

I'll have to leave this for a future debug.. Someone else wants to help out
with this?
