 I got the "Bootstrap comparison failure" error in the log when building
 libgcc at 4.9.2_1 on my 10.4.11 PowerPC. I had interrupted (Ctrl-C) the build
 a couple of times and started it again (with a plain "port build").
 However, after a "port clean" the build finished without problems. I
 suspect this might be a problem in gcc own Makefiles requiring a clean
 build directory for bootstrap.
