    * gdb.texinfo: Mention gzipped exec and core files.

This should mention the name of the node where you make changes; see
the other ChangeLog entries in gdb/doc/.

Do we need a NEWS entry for this?

I'd prefer to say

   in the system-wide temporary directory

and mention neither /tmp nor $TMPDIR, as both are platform-dependent.

I think it might be good to tell people how to specify where the
uncompressed file is located.

Otherwise, the documentation parts are OK.

Thanks.  I'll make the changes.

I agree with Mike that it's better to use library functions for
creating temporary files, since that hides platform dependencies.

The code uses mkstemp() to create a temporary file.  Is there a
GDB or BFD wrapper for this function?
