What's this? Was that intentional?

Yes, it's intentional. _SEH3$_RegisterFrameWithNonVolatiles,
_SEH3$_RegisterFrame, _SEH3$_RegisterTryLevel, etc. all reside in the same
*assembler* source file pseh3_i386.S. Therefore, we can add a reference
to just one of them, and they all will be linked into the program. I use
_SEH3$_RegisterFrameWithNonVolatiles because it was already declared
in pseh3.h.
