10 This hasn't been true for a while now. The latest version of libstdc++ is
11 always used, no matter what version is selected. I can't remember when this
12 was changed but we've gone through a couple GCC stabilizations since.
14 I have no opinion on how to support C++-11, except that it can't be globally
15 enabled. We have to support compilers that predate the standard.
17 I wouldn't like any pkg-config hackery like ICU tried to pull a while back, but
18 now that we have a version of gcc that at least understands the flag in
19 stable at least it wouldn't instantly break everything.
