+	compat: Some compatibility functions and header inclusions.
+	Basic standard C stuff, that may barely be above/around C89.
+
+	The mpg123 code is determined to keep it's legacy. A legacy of old, old UNIX.
+	It is envisioned to include this compat header instead of any of the "standard" headers, to catch compatibility issues.
+	So, don't include stdlib.h or string.h ... include compat.h.
