[doc, fortran] PATCH: address broken web references

[Gerald Pfeifer <gerald at pfeifer dot com>]

This wasn't fun, no fun at all. :-/

Toon, I prefer not to commit this on my own, because you may want to
resolve some of the problems differently.

Would you mind reviewing this and apply it to mainline and on the 3.4
and 3.3 branches (as far as it applies there)?

Gerald


2004-03-14  Gerald Pfeifer  <gerald@pfeifer.com>

	* g77.texi (Aligned Data): Remove obsolete paragraph including a
	broken link.
	(Floating-point Errors): Remove links to http://www.validgh.com/
	which was "hijacked".
	(Language): Fix link to Fortran books.
	(Projects): Remove obsolete paragraph including a broken link to
	ftp://alpha.gnu.org/gnu/g77/projects/.
	(Trouble): Remove obsolete paragraph including a broken link to
	ftp://alpha.gnu.org/g77.plan.

	* invoke.texi (Overall Options): Remove broken reference to
	rat7.uue (which was of dubious copyright status anyways).

	* root.texi (www-burley): Fix URL.
