16 | dnl Most platforms that provide inet_pton define it in libc. |
| 17 | dnl Solaris 8..10 provide inet_pton in libnsl instead. | |
| 35428fb6 LC |
18 | dnl Solaris 2.6..7 provide inet_pton in libresolv instead. |
| 19 | dnl Native Windows provides it in -lws2_32 instead, with a declaration in | |
| 20 | dnl <ws2tcpip.h>, and it uses stdcall calling convention, not cdecl | |
| 21 | dnl (hence we cannot use AC_CHECK_FUNCS, AC_SEARCH_LIBS to find it). | |
