When I try to compile boost 1.33.1 using MSVC 8.0 (VS.net 2005) for a mobile device, I get the following error: H:\PROJECTS\boost_1_33_1\boost/config/compiler/visualc.hpp(133) : fatal error C1189: #error : unknown CE compiler I tried to work around it by changing: # if defined(UNDER_CE) to # if 0 and it seems to work for the most part, except that it looks for certain intrinsic functions (_InterlockedIncrement for example) that apparently aren't available on Windows CE (though the platform API does have them, but not the compiler intrinsic versions). I could probably hack my way around this problem too, but I decided to wait and first ask if there's a more "proper" way to solve this issue. Any ideas?
