00000028 R_ARM_MOVT_PREL .LAlpha

And the encoded instructions in the .o file for main: must be

relative, the 16 bits encoded as part of movw and movt must be both addends,
not addresses. It makes sense to encode addresses by right shifting the value
by 16, but the result is incorrect for PIC.
i.e., the right shift by 16 for movt is ONLY valid for the NON-PCRel case.

This change agrees with what GNU as does, and makes the PIC code run.

Turns out GAS does have Win64 EH directives. (It also supports WinCE EH.) Make

In retrospect, I should have emailed binutils about this earlier. Thanks to
Kai Tietz for pointing out that GAS already had SEH directives.
