Add stdcxx-4.6.1 to libports, fix #339 This patch adds libstdc++ to libports. With the previous version of the stdcxx library, the build system used the C++ standard library that comes with the compiler. This mechanism was prone to inconsistencies of types defined in the header files used at compile time of the tool chain and the types provided by our libc. By building the C++ standard library as part of the Genode build process, such inconsistencies cannot happen anymore. Note that the patch changes the meaning of the 'stdcxx' library for users that happened to rely on 'stdcxx' for hybrid Linux/Genode applications. For such uses, the original mechanism is still available, in the renamed form of 'toolchain_stdcxx'. 2012-08-31 15:13:06 +00:00
