dnl appropriate definitions for template file include/curl/curlbuild.h.in
dnl to properly configure and use the library.
dnl
dnl The need for the curl_socklen_t definition arises mainly to properly
dnl interface HP-UX systems which on one hand have a typedef'ed socklen_t
dnl data type which is 32 or 64-Bit wide depending on the data model being
dnl used, and that on the other hand is only actually used when interfacing
dnl the X/Open sockets provided in the xnet library.
