you mean having 

--hash-style=gnu

as standard for any ld?

i read it would increase speed up to 50%, sounds great! is it backward 
compatible? no, right? how do debuggers deal with this? do they 
already know it? (or we need to update/fix them first?)

ah! more cleanup! if you keep my apostrophe, i'm joining your 
late-summer-cleanup team *big smile* 

sounds interesting :D

means every pkg containing a lib has to be rebuilt? as it is not 
breaking anything, i'm for doing it!

side-question: can we try to rebuild the world on a server with one of 
this fancy auto-build-tools we played some time ago and see how fine 
this works? would mean less uploading and an excellent test-case for 
the auto-build tool, right?

greetings,
