Do you remember what it complained about?  As far as I can remember, I
didn't change the actual code between this version and the last one, but
I may have screwed something up somewhere.  If you can get the errors to
me, I'll see if I can fix it.

Oops... forgot about that.  I'll patch that up.  Actually, these were
only used to make the output slightly prettier, and it may be easiest
just to drop them completely and live with less-than-beautiful output.

They shouldn't anymore, I don't think ... that namespace should only
show up currently for gcc < 3.0.  For other compilers, it shouldn't be
visible.

Can you let me know what declarations it complained about?  If it was
all of them, there may be something else that I need to do to get
gcc-2.95 to play nice.  It may also be a problem with the docs (I may
have left out a macro that you need to define to get it to work
correctly... did you define BOOST_HAS_C99_MATH as well as
BOOST_NONCOMPLIANT_MATH when you compiled?  It may also be a gcc library
issue that requires more workarounds....).
