Re: RFC: support debug info in separate files

Does that mean this feature is not supported by GNU `strip'?  If so, this 
should be reflected in the docs.

`.debug' is an invalid file name on DOS 8+3 filesystems (leading dots are 
not allowed).  For the benefit of users of the DJGPP port of GDB, I 
suggest to allow an additional name, `_debug', as a substitute.  Thus, 
conditioned on __MSDOS__, GDB would look for `_debug' subdirectory if 
`.debug' does not exist.

The doco patch is approved, but please add at least one index entry that 
leads to this information.  Something like

  @cindex separate debug info file

sounds appropriate.

A "@cindex global debug file directory" here would be good.
