# WARNING:

#
#	The vendor hits you...
#	You try to hit the vendor...
#	You die.
#
# Unfortunately the above is no fun...
#
# During testing/porting we have found a long list
# of "make" and "sh" and "awk" features in different implementations.
# Some goodies (make good horror stories for your kids 8-():
#	gmake 3.62
#		non standard target construction
#
#	pmake (e. g. NetBSD on MAC, possible other BNR2+pmake systems)
#		skips '' (empty string positional) args to sh
#		(this leads to following stupid constructions
#		 sh -c "./scripts/makeconfig.sh '$(OS)' '$(COMP)'")
#
#		Following Makefile construction fails for no
#		apparent reason (at least to me)
#		doit:
#			$(MAKE) MAKE=\"$(MAKE)\" all
#
#		all:
#			@echo all done.
#
#		for the "make MAKE=make" call not for "make" or
#		"make -e MAKE=make". Use the last form if you suffer
#		from that kind of make problems. (Easily detected
#		by failure to build with the message:
#		"don't know how to make make".
#
#	sh (Ultrix 4.2 MIPS)
#		shell broken (reversed pipe construction "false | true"
#				 returns false - major bummer)
#
#	awk (EP/IX 2.?)
#		unable to do regexp matches
#		(aka awk '/..*/ { print; }' fails on match)
#
# Usually the vendor should fix these bugs in vital utilities.
# We try to circumvent these bugs in a hopefully portable way.
# If you can reproduce these bugs on your system please bug your
# vendor to fix them. We are not trying anything fancy in here and
# we are shocked that even the most common tools fail so miserably.
# By the time you get this code the above utilities may already
# have been fixed. Hopefully one day we do not have to cope with
# this kind of broken utilities.
#
# Sorry about the situation,
