Hello.

Please find below a patch that adds to the File System Extensions texinfo
docs a description of the interaction of the debug FSEXT and any
user/library FSEXTs.

Bye, Rich =]

  @file{NUL} and @file{CON}, respectively, so you don't need to write
  extensions for these.
  
+ Programs using the DJGPP debug support functions in @file{libdbg.a} may
+ have problems using File System Extensions, because the debug support
+ functions use a File System Extension to track the opening and closing
+ of files.  Only the @code{__FSEXT_open} and @code{__FSEXT_creat}
+ calls will be passed to other File System Extensions by
+ @file{libdbg.a}.  In other words, only fairly trivial File System
+ Extensions can be used in programs at the same time as the debug
+ support functions.
