I assume that one can still build static libraries for Comeau on Win32. In that 
case is it possible that the build process for Comeau in Win32 can be altered to 
only build the static library versions of the respective libraries ?

But one can still define BOOST_ALL_DYN_LINK or BOOST_XXX_DYN_LINK, even
erroneously, when building for Comeau, and this will cause compiler errors.
Perhaps it is not Boost's responsibility for a user's error in defining
BOOST_ALL_DYN_LINK or BOOST_XXX_DYN_LINK but I have discovered, when building 
libraries for Comeau on Win32 in Boost 1.32, two libraries which define 
BOOST_ALL_DYN_LINK for the dll versions of their libraries, date_time and 
program_options.

So what happens is that I build Comeau for Win32 and a slew of errors comes out 
when building the date_time and program_options libraries. I think this needs to 
be derailed somehow.
