Hi,
It looks like this change broke the build, at least for me ;-( The build fails while trying to build libroot with a bunch of undefined references "undefined reference to `__wcsrtombs'". I tried a clean build from a fresh checkout. You can find the log files of the build attempt here:
Same thing here.I have removed "#" before wcsrtombs.c in Jamfile in src/system/libroot/posix/glibc/wcsmbs/.
It builds ok. Still have to test if nothing important is broken ("populating image").
