That discussion is about a different problem, which we don't have in
GDB.  In GDB, the relevant character, DIRNAME_SEPARATOR, is computed
at compile time (not at configure time) in gdb/common/host-defs.h.

> 	      [Directories from which to load auto-loaded scripts.])
> AC_MSG_RESULT([$with_auto_load_dir])

Patches to configure.ac to fix this problem are welcome.  I don't
think we need elaborate logic to compute the character, it's enough to
look at the host name.

Thanks.
