I'm using Boost 1.37 and I've found that using the headers to develop WinCE applications with WinCE causes Boost header config/compiler/visualc.hpp to emit the EVC++ version not recognized.

I've patched the visualc.hpp header to recognize the WinCE/VC9 configuration as follows:

(line 150):

# if defined(UNDER_CE)
#   if _MSC_VER < 1200
      // Note: these are so far off, they are not really supported
#   elif _MSC_VER < 1300 // eVC++ 4 comes with 1200-1202
#     define BOOST_COMPILER_VERSION evc4.0
#   elif _MSC_VER == 1400
#     define BOOST_COMPILER_VERSION evc8
#   elif _MSC_VER == 1500
#    define BOOST_COMPILER_VERSION evc9
#   else
#      if defined(BOOST_ASSERT_CONFIG)
#         error "Unknown EVC++ compiler version - please run the configure tests and report the results"
#      else
#         pragma message("Unknown EVC++ compiler version - please run the configure tests and report the results")
#      endif
#   endif

Thanks, I dont if there's any workaround already available.
