Locale Bug? - was Re: VERY Strange interaction between strcoll, Qt, and locale

[Albert Astals Cid <tsdgeos at terra dot es>]

Hi, look at the sample code (now completely in C) and the result i get

unit.cpp unitdescriptor.cpp -1
unitdescriptor.cpp unit.cpp 1
unit.h unitdescriptor.cpp 4
unitdescriptor.cpp unit.h -4

I think this is a bug because it is not possible that unit.cpp is lower than 
unitdescriptor.cpp and unit.h bigger than unitdescriptor.cpp. Both unit.cpp 
and unit.h should be either bigger or lower than unitdescriptor.cpp 
(depending on dot value in respect with the letters).

Is this a bug that this mailing list can try to verify/fix? If not who/where 
should i report?

Thanks.

Albert.

P.S: I can reproduce the bug also with es_ES instead of ca_ES
