[physfs] Errors...

[Christoph Nelles]

Hi,

i am currently working on the error code stuff and grouped and sorted
the errors defined by PHYSFS. I want to share some odd and interesting
statistics about the errors.

90 (100%) are in my current code
30 (33%) are defined and translated but not used
------

24 (27%) i grouped into platform code only errors
21 (23%) are used only in the OS/2 code
 3 (3%) are for unix, beos, macosx & win
------

14 (16%) are only used by archivers
7 (8%) are only referenced by the zip archiver
-----

5 (6%) are from library management
17 (19%) are considered "generic"

I will try to reduce the number of errors in my private branch at
https://evilazrael.net/hg/hgwebdir.cgi/physfs/shortlog/99c07cb99a39 .
Any suggestions and ideas are welcomed :)


Regards
Christoph
