CVS question

[Bernd Schmidt]

The huge size of egcs-1.0.3a-1.1.diff gave me the idea to try and use the
egcs CVS server for getting a patch against the latest snapshot. The cvsweb
interface apparently only supports generating diffs between two revisions of
a single file. So I examined the histories for tags to use, and used the
following command:

  cvs rdiff -r egcs_ss_19980824 -r egcs_1_1_prerelease egcs

(after logging in, obviously). Unfortunately, I got the response

  cvs [server aborted]: "patch" requires write access to the repository

Can someone enlighten me as to why this needs _write_ access? Am I simply
doing something stupid, or is the rdiff command not supported?
