If you only want to create assembler code, you don't need to compile
libgcc2. As a result, you don't need target header files, either. Of
course, if you use the compiler to compile C code, that C code might
also need header files - which you then would need to provide to users
of the compiler.

Sure.

It looks like there is a bug in your compiler...
