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.
