[m-rev.] for review: add warning about GCC 4.0 to web site

[Ian MacLarty]

For review by anyone.

Estimated hours taken: 0.3

Put warnings about GCC 4.0 on the web site.

download/include/release.inc:
	Add GCC 4.0 to the list of versions of GCC known not to work with
	the current release.
	Remove the comment about GCC 2.7.2 since it doesn't say anything
	useful.

download/include/rotd.inc:
	Remove the comment about stable release of the days being put in the
	beta-releases directory since it's a bit confusing given that the
	beta release is a seperate version.

	Add warning about GCC 4.0.

	Change ROTDS to ROTD since there is only one unstable release of the
	day at any point in time and since the capital S is a little confusing
	-- I thought it might stand for "Source" at first.

include/download.inc:
	Remove the comment about a now old version of Mercury shipping
	with an old version of Debian, since it's unlikely to be meaningful
	to anyone.
