| 9 | # DESCRIPTION | |
| 10 | # | |
| 11 | # This macro figures out what libraries are required on this platform to | |
| 12 | # link sockets programs. | |
| 13 | # | |
| 14 | # The common cases are not to need any extra libraries, or to need | |
| 15 | # -lsocket and -lnsl. We need to avoid linking with libnsl unless we need | |
| 16 | # it, though, since on some OSes where it isn't necessary it will totally | |
| 17 | # break networking. Unisys also includes gethostbyname() in libsocket but | |
| 18 | # needs libnsl for socket(). | |
