Names that mask Fortran intrinsic functions cause errors.

[mbdevpl]

When transpiling between Fortran and Python, declaring for example:

real, parameter :: tiny=1.e-32

and then referencing this name like in:

if (x < tiny .and. x > 0.) then

will cause compiler errors e.g.:

   if (x < tiny() .and. x > 0.0) then
        1
Error: Expected a right parenthesis in expression at (1)
