# AC_ETHEREAL_STRUCT_SA_LEN
#
dnl AC_STRUCT_ST_BLKSIZE extracted from the file in qustion,
dnl "acspecific.m4" in GNU Autoconf 2.12, and turned into
dnl AC_ETHEREAL_STRUCT_SA_LEN, which checks if "struct sockaddr"
dnl has the 4.4BSD "sa_len" member, and defines HAVE_SA_LEN; that's
dnl what's in this file.
dnl Done by Guy Harris <guy@alum.mit.edu> on 1998-11-14.
