The latest version of libstdc++ is always used, no matter what version is selected. I can't remember when this was changed but we've gone through a couple GCC stabilizations since. I have no opinion on how to support C++-11, except that it can't be globally enabled. We have to support compilers that predate the standard. I wouldn't like any pkg-config hackery like ICU tried to pull a while back, but now that we have a version of gcc that at least understands the flag in stable at least it wouldn't instantly break everything. -- Ryan Hill psn: dirtyepic_sk gcc-porting/toolchain/wxwidgets @ gentoo.org 47C3 6D62 4864 0E49 8E9E 7F92 ED38 BD49 957A 8463
