###############################################################################

#
# This file can be included by Open Watcom Makefiles.
# It tests several conditions and defines macros to build
# under DOS, OS/2, Win32 and Linux.
#


#
# The below does not work because the other make-utility *still* processes
# stuff outside the !ifndef and barks on wmake specific constructs.
# This essentially disables forwarding for these other make utils.
# So we prohibit their use altogether.
#
#!ifndef __MAKEFILES__
#front-end:
#	@echo Invoking WMake for $(MAKE)
#	@wmake
#	@echo.
#	@echo == Other Make Utility "$(MAKE)" used, please use "wmake" ==
#	@echo.
#!endif
#

#
# Prohibit processing with other Make Utilities.
# Because WMake expands $(MAKE) to a full path-name, we cannot use it to
# to string-compare it to "wmake". So we assume the __MAKEFILES__ macro
# is unique to WMake. If it's not defined it must be a non-WMake utility.
# GNU Make is not in the list below because it first looks for GNUmakefile.
# Where a Makefile is used, a special GNUmakefile is present that forwards
# to WMake, including selective targets.
