I'm surprised it worked that well. Except for the last one, all the
tests now pass. They shouldn't, since a deficiency with respect to name
resolution should prevent some cmp*.cpp tests from passing (as can be
seen with gcc-2.95.3-linux report). Martin, is the compiler really GCC
2.95 for the STLport tests?

As for the last test (test_float), it seems the compiler does not find
the abs(float) and abs(double) functions. The compilation warning shows
only abs(int) is defined.

I guess the problem lies in the current test code:
#ifndef BOOST_NO_STDC_NAMESPACE
using std::abs;
#endif

I am not so sure it was a good heuristic. So I committed a small patch
that unconditionally put std::abs and std::sqrt in the current namespace
for test/test_float.cpp. My quick tests on Linux don't show any
difference. Let's see how well it behaves on Windows (maybe some
problems with Intel compiler in MSVC6 emulation mode?).

Best regards,
