That is a *precious* observation.  Will actually suspected that problem before 
but you confirm it.

It is true that the clean phase at the start of the automated build actually 
clobbers the bootstrap compiler.  I have inherited the build scripts from the 
previous maintainers and I'm just starting to comprehend how they work or, in 
some case, why they suck.

I'm working on improving the build system to make it work with pristine 
upstream sources using auto-applied patches so that agressive cleaning such 
as it is currently done right now will no longer be necessary.
