As I know -frepo simple force -fno-implicit-templates which rip all template
instantion from all objects and produce additional special files which are
needed for new/additional pre-link compiler call which inject missing
implementation. I'm not expert here but I suppose that gcc will simple build it
even some of those symbols will be available during link.

Sun propose simpler methodology... compiler know during build phase (via
-instlib) what (and what not) templates instance will be available during link
and simple don't emit code for it. There is no special pre-link phase, no
special files only normal linking (and unknown symbols when you don't and
proper -llibs flags).

As I know Sun CC per-default add stl implementation library via -instlib which
reduce build time of know/"prebuild in lib" stl templates instantions.
