Simple file which produces the error

When using range-based for-loops when -nostdinc is given, GCC gives an error
about 'begin' and 'end' not being declared while they definitely are.

I've attached a simple file which produces this error.

Here's the output of "g++ -v -save-temps -std=c++0x -nostdinc main.cpp":

According to the current C++0x draft that loop should call begin(l) and end(l)
but there are no declarations of those functions in your testcase, with or
without -nostdinc

According to the C++0x FDIS your example would work, but that's not implemented
in G++ 4.6.0

Ok I see. Thanks for the clarification!
