| 10 | # We don't want to explicitly mention -lc (since we're using POSIX mode.) |
| 11 | # We also don't want -lx (the Xenix compatability libraries.) The only |
| 12 | # thing that it seems to pick up is chsize(), which has been reported to |
| 13 | # not work. chsize() can also be implemented via fcntl() in perl (if you |
| 14 | # define -D_SYSV3). We'll leave in -lPW since it's harmless. Some |
| 15 | # extension might eventually need it for alloca, though perl doesn't use |
| 16 | # it. |
