smart linking will delete the unused functions. And the environment
substitution feature of the Rtl registry functions is still useful in
kernel mode

no, it's a compiler function. Linkers merge *segments*, they know nothing
about function or object boundaries. The solution: having the compiler
generate one .text segment for each function, one .data segment for each
static object, etc. This is what in Visual C++ is called "COMDATs"

and why this principle can't be applied to the Rtl escapes me

don't blame the sharing of code, blame our recursive makefiles
>IMO, the disadvantages of sharing code outweigh the benefits.
you can't be serious
