I installed egcs from the port.

eg++ produces larger binaries than g++.  From this trivial example, I
would expect these files to be very similar in size.

     obj_size  exe_size   strip_exe_size
     --------  --------   --------------
g++       972      7150             5464
eg++     1188    299547            76792

eg++ seems to produce faster executables.
