Bug#383251: g++-4.1: FTBFS for RQuantLib on i386/testing

[Dirk Eddelbuettel <edd@debian.org>]

(With the 14hr mail outage on master.debian.org, this is the first message I
am seeing in this thread after I filed my bug report. So forgive me if I say
something redundant...).

This is comparable to my experience with RQuantLib.  My last build took 17
minutes wall time in the (unoptimised) pbuilder, so call it a minute for
setting up and closing the pbuilder.

Now, RQuantLib is just five small C++ files ... but it links against the
huge-ish QuantLib.  This used to take maybe minutes, but right now takes
forever. The link step alone is eight minutes (!!) on an aging dual AMD 1.8
MHz --- but with ample 2 GB of RAM. So it's not that I starve g++ and ld of
memory ...
