Hi Raoul,

Thanks for your quick response.

Indeed, updated bug to reflect that. Thanks for the triaging!

Changing the Policy takes quite a long time and current one
also allows exceptions:

---
 10.2 Libraries
... (paragraph about shared libs)

As to the static libraries, the common case is not to have relocatable
code, since there is no benefit, unless in specific cases; therefore the
static version must not be compiled with the -fPIC flag. Any exception
to this rule should be discussed on the mailing list
debian-de...@lists.debian.org, and the reasons for compiling with the
-fPIC flag must be recorded in the file README.Debian. [86]

In other words, if both a shared and a static library is being built,
each source unit (*.c, for example, for C files) will need to be
compiled twice, for the normal case.

I have already asked for many exceptions on d-d:
https://lists.debian.org/debian-devel/2016/09/msg00277.html

If you agree with the proposed change please add i2util to the list and
maybe support the request. It would be nice to see at least one positive
answer to call it a discussion. :-)

I would really love to make the transition happen before the freeze
and asking for exception allowed by the current policy is the most
straightforward way to help that.

Cheers,
Balint
