 support for blocks. Then this port can use gcc to build on PowerPC. It's
 probably unreasonable to expect upstream to abandon the useful blocks
 feature in their code for the benefit of ancient systems, and it's
 probably unreasonable for MacPorts to develop and carry forward forever a
 large patch for this.

 Thank you, Ryan, and I apologize for somehow missing your reply earlier.

 While gcc seems to intend to implement the support for blocks (at least
 according to Iain), I think for the time-being it is better to provide a
 bit earlier version for PowerPC systems. 0.9.0 builds fine.
