----------------------------------------------------------+-----------------
 File libs/numeric/ublas/test/test_complex_norms.cpp includes <cmath> and
 then calls sqrt twice without a std:: qualifier. Although the code works
 with some compilers, it is not portable. The C++ standard says that if you
 include a <cxxx> headaer (like <cmath>) the names in the headers are
 (only) in namespace std.
 Diffs to fix the file:
 {{{
 37c37
 <     const double expected = sqrt(44.0);
 ---
 >     const double expected = std::sqrt(44.0);
 65c65
 <     const float expected = sqrt(44.0);
 ---
 >     const float expected = std::sqrt(44.0);
 }}}
