It is a good idea to define the "feature test macro" _GNU_SOURCE when 
compiling your C files. When you compile on GNU or GNU/Linux, this will 
enable the declarations of GNU library extension functions, and that will 
usually give you a compiler error message if you define the same function 
names in some other way in your program. (You don't have to actually use 
these functions, if you prefer to make the program more portable to other 
systems.)

Just some background info to help the discussion (maybe you all already knew 
this).
