You're welcome. Here are the results.

fpclassify/test> cxx -model ansi -std strict_ansi -nopure_cname -ieee -O4 
-I /vol2/boost/boost test.cpp && ./a.out

fp_traits<float>::type is specialized
fp_traits<double>::type is specialized
fp_traits<long double>::type is generic
sizeof(long double) = 16

Testing float
Testing double
Testing long double

Seems like all tests pass. I tried with all optimization level from 0 to 4. 
I also tried with the command line 'cxx -D__USE_STD_IOSTREAM -O -I 
/vol2/boost/boost test.cpp -lm', meaning it also works in the default 
compiler mode (ansi, and arm object model). You can't leave out -ieee as 
the Alpha needs some special compiler help for conforming IEEE math 
handling, the processor itself is only 'mostly conformant'.
