Hi,
While working on the "reproducible builds" effort [1], we have noticed
that libical could not be built reproducibly.
The attached patch removes randomess caused Perl hash order, resulting
in the generated icalderivedvalue.c file. Once applied, libical can
be
built reproducibly in our reproducible toolchain.
