Yes - this works on Windows but not on Linux!

bjam toolset=gcc architecture=x86 address-model=64 -> does not work
(call vcvars32.bat)
bjam toolset=gcc architecture=x86 instruction-set=yorksfield -> does
work (calls vcvars64.bat)

bjam toolset=msvc-10.0 architecture=86 address-model=64 -> does work
(correct asm)
bjam toolset=msvc-10.0 architecture=86 instruction-set=yorksfield ->
does work (asm not vaild for selected platform)

Why does it behave differently?
