Subject: [boost] regression in math

Very strange: nearly all regression tests failed on my linux platform with g++: (look at linux_x86_64, bronf)
The reason is the always the same but is strange to me:

    "g++" -ftemplate-depth-128 -O0 -fno-inline -Wall -g -mfpmath=sse -mieee-fp -march=nocona -fPIC -Wno-missing-braces -DBOOST_ALL_NO_LIB=1 -DBOOST_REGEX_DYN_LINK=1
-DBOOST_UBLAS_UNSUPPORTED_COMPILER=0 -I".." -c -o "/soft/bal/usr/builds/boost_test/results/boost/bin.v2/libs/math/test/dist_bernoulli_incl_test.test/gcc-3.4.6/debug/dist_bernoulli_incl_test.o"

In file included from ../boost/math/distributions/detail/common_error_handling.hpp:13,
                 from ../boost/math/distributions/bernoulli.hpp:33,
                 from ../libs/math/test/compile_test/dist_bernoulli_incl_test.cpp:9:
../boost/math/special_functions/fpclassify.hpp:170: error: expected unqualified-id before '&&' token

This line has been modified recently and seems not to work now with g++:
