GCC version is 7.2.0 on an OS based on Ubuntu 17.10.

It is probably related to this SO answer, a glibc feature (?) that apparently requires you to #define _DEFAULT_SOURCE as well.

@cxong Tested it and I can confirm that inserting #define _DEFAULT_SOURCE fixes it. If I remember correctly you develop CDogs SDL under OS X and this is a glibc shenanigan.
