 to just leave that and remove the rest. However not too long ago it was
 not possible to build gcc47 on PowerPC; I'm not sure if that was ever
 fixed. Certainly right now would be a poor time to try to test this, since
 other problems have been introduced into the gcc4* ports in the past few
 days that need to be ironed out first, before I go spending days of CPU
 time trying to compile the gcc4* updates on my Power Mac.

 In Fink I could build GCC 4.7.2 on Leopard, Mac OS X 10.5.8, G4. Jack
 Howarth, Fink's maintainer of that package, could build GCC 4.7.2 on a G5.

 My own success is a bit troublesome. The first two tries failed here:

 {{{
         Comparing stages 2 and 3
         warning: gcc/cc1-checksum.o differs
         warning: gcc/cc1obj-checksum.o differs
         warning: gcc/cc1objplus-checksum.o differs
         warning: gcc/cc1plus-checksum.o differs
         Bootstrap comparison failure!
         gcc/host-darwin.o differs
 }}}

 Such files were built then:

 Interestingly I had a disk low warning around the time when the build
 finished with the error message.  At the time when the differing files
 were created the disk had enough space. I then decided to build GCC 4.7.2
 on a different volume, which is used to hold the swap files and was
 intended to also hold virtual systems. While the original volume has HFSX
 with a journal, the other volume has HFS without a journal. The
 compilation on that volume succeeded – like that:

 {{{
         Comparing stages 2 and 3
         warning: gcc/cc1-checksum.o differs
         warning: gcc/cc1obj-checksum.o differs
         warning: gcc/cc1objplus-checksum.o differs
         warning: gcc/cc1plus-checksum.o differs
         Comparison successful.
 }}}

 And then the build process continued with:

 {{{
         if false; then \
           rm -rf stage2-*; \
           echo timestamp >  stage2-lean; \
         fi
 }}}

 In that build I cannot find the stage2-gcc and stage3-gcc directories…

 Last year it succeeded to build GCC 4.7.1.
