-Allow C99-depending features of libstdc++ with uClibc
-
-The libstdc++ code is fairly restrictive on how it checks for C99
-compatibility: it requires *complete* C99 support to enable certain
-features. 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

-
-This patch is similar and highly inspired from

-a way that doesn't involve changing the configure.ac script, as
-autoreconfiguring gcc is complicated. It simply relies on the fact
-that uClibc defines the __UCLIBC__ definition.
