Hello,
I haven't tried to use STL in kernel module. STL is a very
complex library. When I attempted to compile your example,
I also encountered various error, though different from yours.

I forgot to mention in earlier post that I had to typecase -1 to
(unsigned long)-1 in signal.h
I tried to avoid modifying system header files, but found no
other way. Is there an compiler option to turn off only the above warning?
Don't know about other errors you listed, but I was able to avoid
some errors by including vector.h before rtl.h:
----
#define NULL 0
#include <vector.h>
extern "C"
{
#define new _new
#include <rtl.h>
#undef new
}
----
I still get a few "... redefined" warnings but the compilation
completed anyway. The version of my compiler is
egcs-2.91.66, and I am compiling with kernel 2.2.12 hearders.
Is there anyone on this list also on linux kernel dev list?
I understand that there is near to zero probability that linux
kernel will be rewritten in C++, but modifying header files to be
g++/STL safe should not be that complicated.
