Subject: Add AC_C_BIGENDIAN check for <ac/socket.h>.  Code should be rewritten
X-Git-Tag: OPENLDAP_SLAPD_BACK_LDAP~1103
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=a240efce5cbdd31bf98b528cee86de3025e70cfc;p=openldap

Add AC_C_BIGENDIAN check for <ac/socket.h>.  Code should be rewritten
not to require knowledge of byte order such that this check can be removed.
