Allow to catch minor issue with test code.
Although test usually are coded with less care than production
code the current changes required are not so extensive and
can catch different issues.
Most of the patch is making functions static to avoid warnings for
undeclared functions.

Changes sinve v2:
- fix typos;
- extend commit message;
- add a comment in the code to make clear the reason for
  declaration.

Changes since v1:
- was "Compile all tests with same warning level of main server code";
- extend commit message.
