uclibcpp is built as an alternative to the standard libstdc++ library
It provides the support for c++ with a smaller memory footprint.
Right now it depends on newlib, because it has only been tested against newlib

+Minor fixes so uclibcpp compiles.
+
+I have no clude why they wrote the Unwind_Exception_Class variable that way, but that doesn't compile
+
+uclibcpp needs isspace which is not provided otherwise
