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