/[NO]SEPARATE_COMPILATION Controls whether an individual compilation unit becomes a separate module in an object file. The default is /NOSEPARATE_COMPILATION, which groups individual compilation units as a single module in an object file. When creating modules for use in an object library, consider using /SEPARATE_COMPILATION to minimize the size of the routines included by the linker as it creates the executable image. In most cases, the default setting (/NOSEPARATE_COMPILATION) allows more interprocedural optimizations.
