inventing that syntax need ~1minute so this point is IMO void and we dont
even agree that using the english string be it "foobar" or FOOBAR as key 
is a good idea to begin with i for one disagree, and IIRC there where
others who disagreed ...

well such a design would cause noticeable slowdown, because the slow string 
key matching would have to be done for debug messages, think of some bitstream
parsing or similar stuff which generates on the order of gigabytes of output
per minute
so actually string based keys make the decission what should be translatebale
more critical due to the slowdown potential if its done everywhere, OTOH
a simple O(1) array lookup or id==MSGID_DONT_TRASLATE can always be done if 
we want ...

huh?
person1 adds mp_msg() adds entry to the enum adds english entry
no problem

person2 adds mp_msg() adds entry to the enum adds english and german entry
no problem

as long as these patches arent in svn no translation file will contain them
if they are applied to svn their position in the enum list becomes official
again no problem


and about custom versions, they can and should use their own range of numbers
for their private messages
and IMHO we should not try to make it overly easy to fork mplayer, the
more painfull it is to keep large changes in your private mplayer tree the
more patches will get contributed back, we shouldnt shoot ourselfs in the foot

strings always have holes between them unless you use "a","b","c", ... and
using mplayer with old translation files opens a can of worms security
wise, so iam definitly against that unless all strings are checked for 
validity at runtime and this check gurantees that no secholes remain ...

furthermore my suggestion was
static tabel[]={
.[MSGID_FOOBAR]= "Foobar",
...
}

so there are no numbers directly in the translation files and no holes
