Bug #5680: IPPROTO_GGP undeclared when compiling ext/socket/constants.c

On Cygwin, with an unmodified checkout of trunk, I get an error when compiling ext/socket/constants.c, as below.
I'm attaching the constdefs.c file, because this seems relevant, and is autogenerated.

make[2]: Entering directory `/cygdrive/c/Data/ruby-public/ext/socket'
