Warnings from clang 7.0 when compiling dovecot-openssl-common.c from dovecot
2.3.5 with openssl 1.1.1a.
This is dovecot's configuration:
> config_options="--prefix=$prefix \
> --sysconfdir=$prefix/etc \
> --datarootdir=$prefix/share \
> --mandir=$man \
> --docdir=$doc \
> --with-docs \
> --with-ssl=openssl --with-ssldir=$prefix/etc \
> --with-sodium \
> --with-libiconv-prefix=/opt/libiconv \
> \
> --with-bzlib=no \
> --with-gssapi=no \
> --with-ldap=no \
> --with-lucene=no \
> --with-lz4=no \
> --with-lzma=no \
> --with-pam=no \
> --with-solr=no \
> --with-sql=no \
> --with-vpopmail=no \
> --with-zlib=no \
> \
> --enable-dependency-tracking";
Note on passing: --with-ssldir=$prefix/etc is ignored by the configurator, as
it forces $prefix/etc/dovecot.
