[boost] Solaris/gcc integer_traits #error on build

I ran into a problem with the integer_traits.hpp file in the boost 
subdirectory at build time, specifically while trying to build the 
libboost_python-* files. It seems to be the same problem that was 
earlier encountered here: 
http://lists.boost.org/MailArchives/boost/msg76535.php

I downloaded the patched version of integer_traits.hpp from CVS, but the 
problem persisted. I checked the #if statement beginning on line 87 of 
the newer version of the file, and there didn't appear to be any case 
for Solaris. I was building on a Solaris 8 machine, using gcc 3.3.2. I 
modified the file to add another case (line 101):

     87 #ifndef BOOST_NO_INTRINSIC_WCHAR_T
    88 template<>
    89 class integer_traits<wchar_t>
    90   : public std::numeric_limits<wchar_t>,
    91 #if defined(WCHAR_MIN) && defined(WCHAR_MAX)
    92     public detail::integer_traits_base<wchar_t, WCHAR_MIN, 
WCHAR_MAX>
    93 #elif defined(__BORLANDC__) || defined(__CYGWIN__) ||
       defined(__MINGW32_        _) || (defined(__BEOS__) &&
       defined(__GNUC__))
    94     // No WCHAR_MIN and WCHAR_MAX, whar_t is short and unsigned:
    95     public detail::integer_traits_base<wchar_t, 0, 0xffff>
    96 #elif (defined(__sgi) && (!defined(__SGI_STL_PORT) ||
       __SGI_STL_PORT < 0        x400))\
    97     || (defined __APPLE__)\
    98     || (defined(__OpenBSD__) && defined(__GNUC__))\
    99     || (defined(__NetBSD__) && defined(__GNUC__))\
   100     || (defined(__FreeBSD__) && defined(__GNUC__))\
   101     || (defined(__sun__) && defined (__GNUC__) && (__GNUC__ == 3)\
   102     || (defined(__hpux) && defined(__GNUC__) && (__GNUC__ ==
       3) && !defined(__SGI_STL_PORT))
   103     // No WCHAR_MIN and WCHAR_MAX, wchar_t has the same range as 
int.
   104     //  - SGI MIPSpro with native library
   105     //  - gcc 3.x on HP-UX
   106     //  - Mac OS X with native library
   107     //  - gcc on FreeBSD, OpenBSD and NetBSD
   108     public detail::integer_traits_base<wchar_t, INT_MIN, INT_MAX>
   109 #elif defined(__hpux) && defined(__GNUC__) && (__GNUC__ == 2)
       && !defined(__SGI_STL_PORT)
   110     // No WCHAR_MIN and WCHAR_MAX, wchar_t has the same range
       as unsigned int.
   111     //  - gcc 2.95.x on HP-UX
   112     // (also, std::numeric_limits<wchar_t> appears to return
       the wrong values).
   113     public detail::integer_traits_base<wchar_t, 0, UINT_MAX>
   114 #else
   115 #error No WCHAR_MIN and WCHAR_MAX present, please adjust
       integer_traits<        > for your compiler.
   116 #endif
   117 { };
   118 #endif // BOOST_NO_INTRINSIC_WCHAR_T

The file then compiled without a problem when inluded in the python 
libraries. The question I still have is whether this has the potential 
to break something somewhere else in the code.
