Subject: Remove redefinitions of SIG_* macros in win32_port.h.

Remove redefinitions of SIG_* macros in win32_port.h.

It is not clear why these were originally added.  One hypothesis is
that an ancient version of MinGW didn't define them.  In any case,
they appear to now be superfluous, so let's remove them.  If
nothing else, the buildfarm might offer us clues to their origins.
