- References: <1299219720-13398-1-git-send-email-brobecker@adacore.com>
This is the last (code) patch! :) Documentation and NEWS entry
will follow.
It contains the changes needed to configure and build the VxWorks
debugger.
gdb/ChangeLog:
* configure.ac: Add support for vxworks targets.
* configure: Regenerate.
* configure.tgt: Add support for vxworks targets.
* Makefile.in (VXWORKS_CFLAGS): New variable.
(INTERNAL_CFLAGS_BASE): Use VXWORKS_CFLAGS.
