I found this request here: https://gcc.gnu.org/java/projects.html * Write a program to convert existing locale data into a format we can use. I could write it, if you could provide some more info: 1. Do you know where I could get the existing locale data to convert, in a license that is GPL/LGPL compatible? Can I pull it from OpenJDK? 2. What format do you want it converted into? 3. Do you have any requirements for the implementation language? I can write Java (gcj compatible), ISO/ANSI C, C++, Perl, Python, and a whole bunch of languages you're probably not interested in. I would prefer Java. It would take less time to write than C and the program would then work on any system without a recompile. It would work with either gij, OpenJDK, or Oracle's JRE/JDK.
