well, yes, if getopt library itself is not internationalized we can't do 
much about that... besides propose the internationalization yourself; I 
haven't been following the evolution of GNU getopt library for some time 
now... are we sure they haven't internationalized it yet?

well uniformity is quite important, isn't it?

can you make some examples?  I'm not sure I understand

and the corresponding Automake/Autoconf macros for detecting it during 
configure

how would this array be changed?

this would require adding a wrapping function in the generated code, right?

For the moment, I cannot add any new feature to gengetopt myself: it's 
such a busy moment that I really can't work on it... especially if it 
requires to write C code (as opposite to C++ code), as in the case of 
the runtime wrapping...

Of course, if you can provide patches (and unit test cases) I'll be 
happy to collaborate :)
