Re: [Plplot-devel] Problem on Windows with gfortran and the Fortran 95 bindings

[Arjen M. <arj...@de...>]

Hi Alan,

I have removed the platform-dependent files:
It turns out that the problem was due to the specific distribution
of the gfortran compiler I had chosen, not to the version.

(I still need to make a note of that in the release notes).

Anyway, I can proceed now with the renovation of the Fortran 95
examples and bindings.

Regards,

Arjen
