Part of our module implementation adds a sample mapper server, the guts of which are used by the default in-process mapping of cc1plus. Rather than add another executable to gcc/cp/, this creates a new c++tools directory where this and any other c++ tools might live. The toplevel changes are a subsequent commit, because ... git. c++tools/ChangeLog: * Makefile.in: New. * config.h.in: New. * configure: New. * configure.ac: New. * resolver.cc: New. * resolver.h: New. * server.cc: New.
