Re: Any objections to swapping base compilers to make gcc4.7 the default?

[John Marino <dragonflybsd@xxxxxxxxx>]

So
1) They are broken permanently until A) somebody patches them or B) 
somebody updates the package which has a good chance of working with gcc47
2) They aren't broken if you use DRAGONFLY_CCVER=gcc44 which we have 
done in the pkg themselves for those pkgs hopelessly broken on gcc4.7. 
The ones that can be patches do not feature this.  That shouldn't stop 
people from using DRAGONFLY_CCVER on packages known to previously build. 
  It's a legitimate technique.
3) this is the latest excerpt bulk build (follows)
The gnustep-base is a separate multiplatform-disaster.  The rest of the 
failures are leaf packages.  Nothing too major.  Building with gcc44 
probably gets you another 100 packages I would think, at most.
