+// if CGO_ENABLED=0 import fakecgo to setup the Cgo runtime correctly.
+// This is required since some frameworks need TLS setup the C way which Go doesn't do.
+// We currently don't support ios in fakecgo mode so force Cgo or fail
+//
+// The way that the Cgo runtime (runtime/cgo) works is by setting some variables found
+// in runtime with non-null GCC compiled functions. The variables that are replaced are
+// var (
+//		iscgo             bool 							// in runtime/cgo.go
+//		_cgo_init         unsafe.Pointer 				// in runtime/cgo.go
+//		_cgo_thread_start unsafe.Pointer				// in runtime/cgo.go
+//		_cgo_notify_runtime_init_done unsafe.Pointer 	// in runtime/cgo.go
+//		_cgo_setenv unsafe.Pointer  					// in runtime/env_posix.go
+//		_cgo_unsetenv unsafe.Pointer					// in runtime/env_posix.go
+// )
+// importing fakecgo will set these (using //go:linkname) with functions written
+// entirely in Go (except for some assembly trampolines to change GCC ABI to Go ABI).
+// Doing so makes it possible to build applications that call into C without CGO_ENABLED=1.
