Just to add some further prophecy to this: with GCC 4.6 the gfortran compiler became a complete implementation of Fortran 2003. This allows for Object Oriented Programming (OOP), the fashionable style of designing code these days. This means that there could well be more new software written in Fortran; without a Fortran compiler a user will be unable to install this code on a source-based distro like Gentoo. > After all, gentoo is a source based distribution.

Indeed, the ability to compile as many languages as possible is almost a necessity for users of a source-based system like Gentoo. --=20 Regards, Dave [RLU #314465] *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* dwnoon@ntlworld.com (David W Noon) *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* --Sig_/zCfcp.rKoOyvWYk_jMCc+Sy Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (GNU/Linux) iEYEARECAAYFAk4E6jcACgkQc9/LpQ70v4/vfQCfZm8ND4xL4HpL0euXveTlIu9N 4b0AniqrUSi5s3bhSxchFpBZ5GUJJ+Ey =D6XL -----END PGP SIGNATURE----- --Sig_/zCfcp.rKoOyvWYk_jMCc+Sy--
