Any up-to-date references for replacing the MS CRT?

I've used this as a reference, but it doesn't appear to be complete. When I set /NODEFAULTLIB, I get linker errors about missing __except_list, __load_config_used, and a few other things apparently related to SEH. It's easy enough to get _CxxThrowException and friends linked correctly, but I have no idea what __except_list is supposed to be and I don't know where to start looking.

I'm using both MSC and IC. When using IC, the linker reports __except_list as missing, though this is not the case with MSC.

For those of you who's favorite answer is "why?": It's because I want to know how this works, and I'm tired of do-nothing test applications starting life with 300kb committed for absolutely no reason.

linker option /safeseh:no (look at IMAGE_LOAD_CONFIG_DIRECTORY in PE image info).

If you want to get rid of CRT dependency, then pass /Zl option to the compiler. Linker does not need any special options (compiler won't insert /DEFAULTLIB:... into .drectve section, so linker won't bind your EXE to any CRT). Of course you shouldn't be using C++ exceptions or heap in your code; or you need to provide your own version of library functions written in assembly language.
