If it's Windows host, the answer is: plugin support relies on dlopen, and 
on -rdynamic for plugins to access symbols from cc1/cc1plus.  No doubt it 
would be possible to add Windows host support, but it would require 
someone with a thorough understanding of the Windows DLL model and how it 
differs from ELF shared libraries to come up with and implement an 
appropriate design for Windows-host plugins in GCC.
