There are a lot of inscrutable failures from the Teeks machines running 
GCC on linux that I'm unable to reproduce (and aren't reproduced by 
other testers), for example: 
http://www.boost.org/development/tests/develop/developer/output/teeks99-03d-Ubuntu12-04-64-boost-bin-v2-libs-multiprecision-test-ublas5_et-test-gcc-4-7-debug.html

All the failures refer to is_convertible, and have an instantiation back 
trace that leads nowhere (a line that doesn't instantiate anything, and 
which refers to Boost.Range which multiprecision doesn't use).  I see 
similar failures in the spirit tests as well.  Is anyone able to 
reproduce these?  Any ideas what may be going on?  The failures are on 
the master branch as well if that helps.

Many thanks, John.
