Well, that's a (tiny) start... however:

* I wouldn't have found it if you wouldn't have provided the link - and I did
search the Wiki (albeit not very thoroughly)
* I think that has low search engine visibility
* I believe there should be some auto-generated skeleton of that (either a
single page or multiple pages) which collects all error messages.
* I would definitely separate the language-specific errors for different
languages  (perhaps an even finer separation into pages is called for, but
certainly at least that)

Fair enough, but, honestly - if the page says "Please, feel free to suggest new
content in gcc-help mailing list" - practically nobody will contribute.

Also, I'm sure that some of this could be adapted from from other sources
online.
