[Dovecot] crypt missing (configure problem)

[Fabio Busatto]

Hi, I need some feedback for the following problem I encountered
compiling dovecot.

It seems to be a wrong check in configure, that comes out in a fatal
error (crypt symbol not found because the -lcrypt is omitted).
With these configure parameters no crypt module is recognized (and so
the need_crypt variable is still off), but at compile time gcc fails
to create executables.

I solve the issue forcing the need_crypt variable to on in configure,
but maybe it can be solved clearly adding the right checks.

Here is some info:
Dovecot: tested on 1.0.rc17 and 1.0.rc27
OS: linux
Configuration parameters: ./configure --without-passwd \
                                      --without-passwd-file \
                                      --without-shadow \
                                      --without-pam \
                                      --without-bsdauth \
                                      --without-gssapi \
                                      --without-sia \
                                      --without-ldap \
                                      --without-vpopmail \
                                      --without-static-userdb \
                                      --without-sql \
                                      --without-pgsql \
                                      --without-mysql \
                                      --without-sqlite \
                                      --without-deliver \
                                      --without-sql-drivers \
                                      --with-storages=maildir \
                                      --disable-ipv6

Here there are the errors:
