Warnings come from configure.in. I use these lines

AC_CONFIG_SUBDIRS(tools/$NCURSES)
AC_CONFIG_SUBDIRS(tools/$READLINE)
AC_CONFIG_SUBDIRS(tools/$GSL)
AC_CONFIG_SUBDIRS(tools/$GPP)
AC_CONFIG_SUBDIRS(tools/$FILE)
AC_CONFIG_SUBDIRS(tools/$ICONV)
AC_CONFIG_SUBDIRS(tools/$SQLITE)
AC_CONFIG_SUBDIRS(tools/$UNITS)

to configure packages in tools directory. I don't know any other 
solution to configure these packages and I don't know how configure 
itself complaims about these lines.

	You have to use GNU make. These patterns are allowed by gmake.

	These warnings are not signifiant. I only rewrite default rules.
