For example, uClibc provides a good number of C99 features, -but not C99 complex number support. For this reason, libstdc++ -completely disables many the standard C++ methods that can in fact -work because uClibc provides the necessary functions. - -This patch is similar and highly inspired from -https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58393, but implemented in -a way that doesn't involve changing the configure.ac script, as -autoreconfiguring gcc is complicated.
