Mr. Erwin some how has a nice sound to it , but the Erwin part would be
more than enough :-)
It doesn't like certain assembler constructs. When you could do is make
a header file with only the prototypes of the functions you need. For
example the
extern "C" void __set_64bit(long long unsigned int *, unsigned int,
unsigned int);
That header file you can than include in C++ source files. If the
functions (__set_64bit in the example here) is a macro or a static
inline, one can make a C file that has the body of the function.
You might look on the net for references on how to write kernel modules
in C++ because this is not just an RTL problem. I believe some ppl out
there wrote some help functions in dealing with this.
