I would suggest in fact: if any host-side code moves to a separate 
library, even if the library has messages needing translation it should 
*not* get its own translation domain unless and until some non-GCC 
software starts using the library.  Instead, exgettext should be taught to 
find the relevant source files if needed (or the gettext invocation for 
cpplib should be so taught, if applicable), so the messages remain in the 
gcc or cpplib domains.

I don't think it belongs to such a shared library, because it is specific 
to the concepts of the C/C++ preprocessor.  Other languages may have 
different concepts for nested contexts in which a diagnostic is given, in 
which case different text will be needed.
