Hi

I've been helping somebody along with getting the new libcrypt going,
and something has broken recently (post-egcs?), and I'm having a wee
problem debugging it.

Libcrypt uses routines out of libmd (MD[45]* and SHA*), and a while
back (pre-egcs), it was possible to have an "LDADD+=-lmd" in libcrypt's
Makefile and have anything using libcrypt also automagically pick up the
-lmd dependancy requirement. This no longer seems to work:

cc -O -pipe -I/usr/src/gnu/usr.bin/perl/miniperl/../../../../contrib/perl5 -I/usr/obj/usr/src/gnu/usr.bin/perl/miniperl   -I/usr/obj/usr/src/tmp/usr/include -c /usr/src/gnu/usr.bin/perl/miniperl/../../../../contrib/perl5/miniperlmain.c
cc -O -pipe -I/usr/src/gnu/usr.bin/perl/miniperl/../../../../contrib/perl5 -I/usr/obj/usr/src/gnu/usr.bin/perl/miniperl   -I/usr/obj/usr/src/tmp/usr/include  -static -o miniperl miniperlmain.o  -lperl -lm -lcrypt
/usr/obj/usr/src/tmp/usr/lib/libcrypt.a(crypt-shs.o): In function `crypt_shs':
crypt-shs.o(.text+0x11): undefined reference to `SHA_Init'
crypt-shs.o(.text+0x1f): undefined reference to `SHA_Update'
crypt-shs.o(.text+0x3c): undefined reference to `SHA_Update'

The "undefined references" are all in libmd which is listed as above
in libcrypt's Makefile.

I would hate to have to hunt down all usages of -lcrypt to add -lmd.

Any ideas?
