commit    0dc9c7d200e59b19b2e683f78afa1ee4cfcf3c21
Author:   Nathan Bossart <nathan@postgresql.org>

First released in: 18.0

    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.
