Fix macro-redefinition warning on MSVC.

In commit 9d6b160, I tweaked pg_config.h.win32 to use "#define HAVE_LONG_LONG_INT_64 1" rather than defining it as empty, for consistency with what happens in an autoconf'd build. But Solution.pm injects another definition of that macro into ecpg_config.h, leading to justifiable (though harmless) compiler whining. Make that one consistent too. Back-patch, like the previous patch. Discussion: https://postgr.es/m/CAEepm=1dWsXROuSbRg8PbKLh0S=8Ou-V8sr05DxmJOF5chBxqQ@mail.gmail.com
