This is horribly misleading. Clang is a perfectly reasonable C++98/03 compiler on Linux.

The issues you ran into concern C++0x, where the world is much messier. The C++0x situation on Linux is admittedly frustrating because of library issues:
	- libstdc++ <= 4.4 doesn't work with a C++0x compiler that implements the current WP's formulation of rvalue references. Jeffrey Yasskin provided a patch for this.
	- libc++ hasn't been fully ported to Linux
	- libstdc++ >= 4.5 has an issue with generalized initializer lists; I worked around that problem in Clang, but I don't know if this is the last problem with these libraries or just the first.
