>Description:

- Add WITH_PGO to build with Profile-Guided Optimization
- Profile-Guided Optimization build support is off per default

Port maintainer (hideo at lastamericanempire.com) is cc'd.

Generated with FreeBSD Port Tools 0.77

- For information on Profile-Guided Optimization:

http://en.wikipedia.org/wiki/Profile-guided_optimization

------- RECIPE
	1) Compile everything with CFLAGS/LDFLAGS containing
	  '-fprofile-generate';

	2) Run lots of test cases to generate profiling information;

	3) Remove all binaries leaving only the profiling information behind;

	4) Replace all instances of '-fprofile-generate' with
	   '-fprofile-use';

	5) Re-compile everything using the profiling information.
