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.
