Get typename of a variable without any common libraries?

[Varscott11]

This may be asking much, but is it at all possible to get the typename of a variable without using common libraries? The reason is that I am writing an OS, and need to write all of these basic functions from scratch. Any ideas?

No. #include <typeinfo> is required if we want to use the typeid operator.

Note: with g++ (-freestanding), we would still get <typeinfo> support with libsupc++
