#	check for add-on CFLAGS and CXXFLAGS
#
#	Rules:
#	1) USR_CFLAGS is used
#	2) if there is a special USR_CFLAGS_$(OS_CLASS), it's
#	   appended to 1)
#	3) if there is no special defined, but a generic USR_CFLAGS_DEFAULT,
#	   this one is appended
#	4) if you have the special case that your USR_CFLAGS_$(OS_CLASS) is
#	   empty but you don't want 3), you have to define it as '-nil-', e.g.:
#		USR_CFLAGS = <defines for all systems>
#		USR_CFLAGS_sun4 = -nil-
#		USR_CFLAGS_DEFAULT = <defines for most systems, not sun4>
#
#	These rules apply to these Makefile-variables:
#	USR_CFLAGS	C flags
#	USR_CXXFLAGS	C++ flags
#	USR_CPPFLAGS	c preprocesser flags
#	INC		include-files to install
#	LIBSRCS		source files for building library
#	PROD_LIBS	EPICS libs needed by PROD and TESTPROD
#	USR_LIBS	NONEPICS libs needed by PROD and TESTPROD
#	USR_LDFLAGS	ld flags
#	SYS_PROD_LIBS	system libs needed by PROD and TESTPROD
#	PROD		products to build and install
#	SCRIPTS		scripts to install
#	USR_INCLUDES	include directories
#
#	Remark:
#	If you define INC, e.g. INC = getopt.h, the source
#	(getopt.h) must be in the source directory (..) and/or
#	in one or more ../os/<OS_CLASS> directories.
#	The INC source files cannot be created by the build.
