dnl Synopsis:	mdw_DEFINE_PATHS(CODE)
dnl
dnl Arguments:	CODE = shell script code to execute
dnl
dnl Use:	Fixes up various variables so that pathname defines can be
dnl		defined.  Within CODE, you may use the following macros:
dnl
dnl		mdw_PROG(NAME)		Transformed program name
dnl
dnl		mdw_PATH(PATH)		Expanded path (may contain variables)
dnl
dnl		mdw_DEFINE_PROG(SYMBOL, PROG)
dnl					Define a symbol as a transformed
dnl					program name.
dnl
dnl		mdw_DEFINE_PATH(SYMBOL, NAME)
dnl					Define a symbol as an expanded path
