  Otherwise, 

This is good.  I have three comments:

 . in the @cindex entries, I think it's better to use "structure
   fields" instead of just "fields", at least in one of them;

 . please use @kbd{M-?}, not @key (there's no key labeled literally
   with M-?);

 . not every GDB user knows by heart the definition of the ui_file
   structure, so I'd add the following passage right after your text:

 @noindent
 This is because the @code{gdb_stdout} is a variable of the type
 @code{struct ui_file} that is defined in @value{GDBN} sources as
 follows:

 @smallexample
 struct ui_file
 @{
    int *magic;
    ui_file_flush_ftype *to_flush;
    ui_file_write_ftype *to_write;
    ui_file_fputs_ftype *to_fputs;
    ui_file_read_ftype *to_read;
    ui_file_delete_ftype *to_delete;
    ui_file_isatty_ftype *to_isatty;
    ui_file_rewind_ftype *to_rewind;
    ui_file_put_ftype *to_put;
    void *to_data;
