Good point ... seems like we lost *all* CFLAGS not just the SSE42 ones.
I believe the options we see here are all from CPPFLAGS not CFLAGS.
Terry, could we see a full "make" trace from src/port/? Something like
cd src/port
make -s clean
make
I'm curious whether the flags lossage affects all .c files in that
directory, or only ones that are trying to add on custom flags.
regards, tom lane
