cross-compiling is a little bit problematic. Please note that Windows CE on
ARM is not supported yet (if I find time I'll implement the calling
conventions for this platform).

File libs/context/config/x86.cpp identifies the x86 architecture (your
cross-compiler environment is required to simulate WinCE on x86).
x86.cpp contains macros defined by several compilers for x86. Regarding to
http://msdn.microsoft.com/en-us/library/aa449784.aspx Windows CE defines
_M_IX86 for this purpose - but this macro is already contained by x86.cpp -
therefore I assume that your cross-compiler env. is not correct/complete.

Maybe you can write a little test-app checking for this macro:

#include <iostream>

int main( int argc, char * argv[]) {
#if defined (_M_IX86)
  std::cout << "_M_IX86 defined\n";
#else
  std::cout << "_M_IX86 not defined\n";
#endif

  return 0;
}

Oliver
