Good question !

I generally do a double bootstrap in which my first build is done with a
previous version of GCC. Once I see reasonable testsuite results I then
use the resultant compiler from the first bootstrap to build the "release"
version. This then explains why the compiler that build GCC 4.5.1 on
Solaris 8 is in fact, GCC 4.5.1 :

http://gcc.gnu.org/ml/gcc-testresults/2010-09/msg02183.html

However, having said all this I have yet to see either the ppl or cloog
software components build once on the legacy Solaris platform I must
support baseline legacy Solaris 8 which in turn assures functionality
upwards to Solaris 10 and possibly 11.
