I have seen one in std.regex!  It's a good idea.

In this case, I can't use verison blocks.  The unittests fail on Gentoo
Linux, however they succeed on some other Linux systems. version
(Linux) will bypass the unittests on all Linux systems.

I think I can add try-catch blocks instead:
--------------------
try
{
    r = to!real(to!string(real.min_normal));
    assert(to!string(r) == to!string(real.min_normal));
}
catch (ConvError e)    // strtold() bug on some platforms
{
    printf(" --- std.math(%u) broken test ---\n", cast(uint) __LINE__);
}
--------------------
If there's no problem, I'll commit this after.

Thank you for the advice!
