Gennadiy,

I've prepared a simple workaround for missing snprintf and vsnprintf
functions. Patch attached to the ticket [1]

Due to the fact that these functions are used not only in Boost.Test,
I thought it may be a good idea Boost.Config gives some hints about
their availability, so I also updated boost/config/platform/linux.hpp
with two definitions for Linux && Comeau

#  define BOOST_NO_SNPRINTF
#  define BOOST_NO_VSNPRINTF

I have very little knowledge about internals of Boost.Config,
so I'm not sure if that is proper approach.

By the way, I also submitted new ticket [2] with small patch
that enables POSIX/SVID support for Comeau toolset.

To summary, these two patches fix the related problems,
however I found some further issues which I'm investigating,
and hopefully, patching.
