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.
