#serial 4

dnl See if there's a working, system-supplied version of the getline function.
dnl We can't just do AC_REPLACE_FUNCS(getline) because some systems
dnl have a function by that name in -linet that doesn't have anything
dnl to do with the function we need.

[dnl
  am_getline_needs_run_time_check=no
