[uclibc-ng-devel] [PATCH] fix uClibc-ng scanf check

uClibc-ng tries to be compatible with GNU libc and defines __GLIBC__ and pretend to be version 2.2. We once changed it to 2.10, but then some hard to fix problems in different software packages (gcc) occured. It would be better if we disable the special GNU libc checks for uClibc-ng here. uClibc-ng implements the required scanf functionality.
