# crypt() may or may not be available, for instance in some countries there
# are restrictions on cryptography.
#
# crypt() might be in libc (eg. OpenBSD), or it might be in a separate
# -lcrypt library (eg. Debian GNU/Linux).
#
# On HP-UX 11, crypt() is in libc and there's a dummy libcrypt.a. We must
# be careful to avoid -lcrypt in this case, since libtool will see there's
# only a static libcrypt and decide to build only a static libguile.
#
# AC_SEARCH_LIBS lets us add -lcrypt to LIBS only if crypt() is not in the
# libraries already in that list.
