If you are ready for another backwards compatibility break and lots of new "challenges" I've created a simple experimental build with newlib 1.17.0 which improves:
* new C99 wide-char function additions
* movement of regex functions from sys/linux directory into shared libc/posix directory
* string function optimizations
* redesign of formatted I/O to reduce dependencies when using sprintf/sscanf family of functions
* numerous warning cleanups
* various bug fixes
The build can be downloaded here: https://sourceforge.net/project/showfil ... _id=657348
I'll add the patch to SVN soon after this post!
