Are native modules subject to LTCG optimizations?

The VC++ 2003 linker can perform cross-module optimizations if it has
been invoked with the /LTCG option. Do such optimizations apply to
native modules (.obj and .lib files compiled without /LTCG) as well?

/LTCG is _linker_ switch, so it's impossible to specify
/LTCG for compiler. There is /GL switch for compiler to make
binaries suitable for further link-time code generation by
linker.
