dnl ##
dnl ## Synopsis:
dnl ## AC_CHECK_PTH([MIN-VERSION [, # minimum Pth version, e.g. 1.2.0
dnl ## DEFAULT-WITH-PTH [, # default value for --with-pth option
dnl ## DEFAULT-WITH-PTH-TEST [,# default value for --with-pth-test option
dnl ## EXTEND-VARS [, # whether CFLAGS/LDFLAGS/etc are extended
dnl ## ACTION-IF-FOUND [, # action to perform if Pth was found
dnl ## ACTION-IF-NOT-FOUND # action to perform if Pth was not found
dnl ## ]]]]]])
dnl ## Examples:
dnl ## AC_CHECK_PTH(1.2.0)
dnl ## AC_CHECK_PTH(1.2.0,,,no,CFLAGS="$CFLAGS -DHAVE_PTH $PTH_CFLAGS")
