Compiler error while buidling pre2

Hi!

prompted by the recent mails, I started an upgrade on my sparc32 and 
sparc64 systems! It is still cool enough to try :)

On Sparc32 I get a fairly early failure:

the error is consistent, both if I resume make or if I do a clean and 
restart!

Having an eye on top while compilation, I see that not all swap or 
memory is consumed. Anybody else sees the problem ?
