Currently I'm trying to do quite the opposite: use object files produced
with GCC/binutils for arm-wince-pe target as an input to MS linker.
What I see is binutils' sources for the target are rather crude and the
object files produced are incompatible with MS COFF PE format in many
ways. So, you should be prepared to all the sort of problems like
incompatible relocations info and sections flags, etc. On the other
hand, binutils may be less restrictive and more robust to object
file incompatibilities. It is IMHO, since I'm not the expert in
binutils.
