AC_CHECK_LIB(c_r, gethostbyname_r)
dnl We don't want to link with libdl even if it's present on OS X, since
dnl it's not used and not part of the default installation. OS/2 has dlfcn
dnl in libc.
dnl We don't want to link against libm or libpthread on Darwin since
dnl they both are just symlinks to libSystem and explicitly linking
dnl against libSystem causes issues when debugging (see bug 299601).
