Comment (by konis at stats.ox.ac.uk):

 There was a message on the R-SIG-MAC list
 (https://stat.ethz.ch/pipermail/r-sig-mac/2008-April/004776.html) a while
 ago saying that OS X 10.5.3 is going to include a stable gfortran. If this
 turns out to be true then I want to get rid of the dependency on gccXX
 altogether. Since anyone using the R port presumably already has gcc42
 installed I don't want to make them update to gcc43 only to have the
 dependency removed in a few weeks. Perhaps we could leave gcc42 as the
 default for now - I can make gcc43 the default for 10.4.x in a revision
 after 10.5.3 is available.

 Otherwise I am happy with all the changes you made. Thanks.
