Is there a way to use c++11 features in sourcemod extensions without SourceMod complaining about undefined symbol?

The game (and thus SourceMod) isn't compiled against stdlib, but rather Valve's version of it (vstdlib).

There is no relation between stdlib and vstdlib other than similar names. Valve compile against stdlib, but we do not due to ABI differences between versions. They work around that to an extent by shipping a copy of libstdc++.so.6 with most of their game servers and using LD_LIBRARY_PATH to override the system copy.

You might want to take a look at what AMBuild2 is doing in bug 6143.

Edit: Although I guess that's technically linking, not compiling.

I misspoke. We link against it but avoid using features from it where possible.
