My dream is not so noisy ;)

my "boostrap patch" assume that the base system is correct.
Some patchs are needed to this base system even if you use pkgsrc or not.
You need thoses patches before the bootstrap.
I think my patch solve the ABI issue in mk.conf , setting ABI=64 when needed.
Please read pkgsrc guide 3.3.7.2 , that is for sunpro. why not gcc?
The most important things of my boostrap patch , is to create to new arch
sparc64 and x86_64 needed by some packages like multimedia packages.
I test my boostrap patch on 4 builds on almost 800 packages.
     sparc
     sparc64
     i386
     x86_64

It works fine.
is my dream more noisy? ;)

Cheers,
Gilles
