Reviewed GLFW compilation requirements on Linux: `_GNU_SOURCE`
Reasons to NOT define `_GNU_SOURCE`:
- access to lots of nonstandard GNU/Linux extension functions
- access to traditional functions which were omitted from the POSIX standard (often for good reason, such as being replaced with better alternatives, or being tied to particular legacy implementations)
- access to low-level functions that cannot be portable, but that you sometimes need for implementing system utilities like mount, ifconfig, etc.
- broken behavior for lots of POSIX-specified functions, where the GNU folks disagreed with the standards committee on how the functions should behave and decided to do their own thing.
