- See doc/windows
* Rename config.mk to global.mk
- Avoid name collision (cascade includes in rules.mk)
* Added ${EXT_EXE} in some test program directories
* Split rules.mk into config.mk
- Some scripts just need to get the environ (config.mk)
- They dont need the rules
--HG--
rename : config.mk => global.mk
