dnl SED is needed by some of the tools

AC_PATH_PROG( SED, sed, , $PATH:/usr/bin:/usr/local/bin)

AC_PATH_PROG( SED, sed, sed-was-not-found-by-configure,

              $PATH:/usr/bin:/usr/local/bin)

AC_SUBST(SED)

if test "x$SED" = "xsed-was-not-found-by-configure"; then

  AC_MSG_WARN([sed was not found, this may ruin your chances to build fine])

fi

dnl AR is used by libtool, and try the odd Solaris path too

AC_PATH_PROG( AR, ar, , $PATH:/usr/bin:/usr/local/bin:/usr/ccs/bin)

AC_PATH_PROG( AR, ar,

              ar-was-not-found-by-configure,

              $PATH:/usr/bin:/usr/local/bin:/usr/ccs/bin)

AC_SUBST(AR)

if test "x$AR" = "xar-was-not-found-by-configure"; then

  AC_MSG_WARN([ar was not found, this may ruin your chances to build fine])
