[news.eclipse.tools.cdt] Overriding default content types

[Ethan T <eclipse@xxxxxxxxxxxxxx>]

I originally posted this in .newcomer, but since it seems to be CDT
specific, I'll repost here:

I'd like to start coding for Rabbit microprocessors with Eclipse, but
I'm having problems with a file type setting. This is a language called
"Dynamic C" which is close enough to C that it should be usable in Eclipse.

However, Rabbit uses ".lib" to identify libraries in source code format.
These are ASCII source files, rather than the normal static libraries
we're used to seeing in other C environments.

Unfortunately, when I make a custom file type in the CDT to set "*.lib"
to "C Source File", it saves the setting but nothing changes. Eclipse
still thinks they're static libraries, and thus doesn't color code the
file or analyze the code for its functions and definitions.

Is it possible to disable or override the default ".lib" content type so
that I can use my own?
