LC_NUMERC?

[Andreas Beyer]

I guess the American standard (== C-locale) is virtually an 
international standard. So, we might go for the C-locale in case of 
LC_NUMERIC. In any case this should only be the default! The makefiles 
should have an option to set the locale explicitely. Thus, in order to 
communicate with gnuplot we would still have to set the C-locale 
explicitely (and set it back afterwards). The makefile should allow for 
something like

# set this to 0 to use your local number representation in data files
USE_C_LOCALE 1
[...]
gcc [...] $(USE_C_LOCALE)

There could be people relying on the fact that statist uses their own 
locale when reading data. E.g. MSExcel uses the country specific 
settings. If someone exports data from there, he/she will not 
necessarily get files that are compatible with the C-locale.
Anyway it seems better not to change the entire locale when sending data 
to gnuplot. Otherwise also (error-)messages would be printed in English 
during this phase. That would be a petty after all these translation 
efforts. ;-) Thus, we should definitely only change LC_NUMERIC.
