Patches should be sent to gdb-patches@ (redirected).

Thanks.

Later we should probably have a user option to control that.

Yes, IMO.

I don't like its starting with an underline.  This is a normal
variable, no need to pretend it's internal or something.

Please use the GNU style of brace-placing.

Ditto.

This is not the GNU style of comments.

I'm not sure what The Powers That Be think about defining inline
functions in a header.  In general, if a host does not support the
`inline' keyword, it will be defined away, so you get several
identically-named functions in the same program (although I think
`static' prevents them from causing a link error).
