# Note [Windows Exception Handling]
# sjlj (short jump long jump) exception handling makes no sense on x86_64,
# it's forcably slowing programs down as it produces a constant overhead.
# On x86_64 we have SEH (Structured Exception Handling) and we should use
# that. On i686, we do not have SEH, and have to use sjlj with dwarf2.
# Hence it's now conditional on x86_32 (i686 is 32bit).
