Hello Oliver

I see you have committed some warning fixes. I just wanted to mention
the reinterpret_cast<void *> in seh.cpp was there to avoid GCC being too
clever for its own good:

..\..\..\libs\context\src\seh.cpp: In function const char*
exception_description(const _EXCEPTION_RECORD*, char*, size_t):
..\..\..\libs\context\src\seh.cpp:36:82: warning: format %p expects type
void*, but argument 5 has type ULONG_PTR

Any thoughts on the build failure though? Just to clarify: I'm using
Cygwin's x86_64-w64-mingw32-g++ GCC and MASM from VS2010. My
user-config.jam has:

using gcc : 4.5 : c:\\cygwin\\bin\\x86_64-w64-mingw32-g++ ;

Then compiling with bjam --toolset=gcc from a VS2010 x64 environment:

Performing configuration checks

    - 32-bit                   : no
    - 64-bit                   : yes
    - x86                      : yes
