+/* Simplified large file handling.
+	I used to have a check here that prevents building for a library with conflicting large file setup
+	(application that uses 32 bit offsets with library that uses 64 bits).
+	While that was perfectly fine in an environment where there is one incarnation of the library,
+	it hurt GNU/Linux and Solaris systems with multilib where the distribution fails to provide the
+	correct header matching the 32 bit library (where large files need explicit support) or
+	the 64 bit library (where there is no distinction).
+
+	New approach: When the app defines _FILE_OFFSET_BITS, it wants non-default large file support,
+	and thus functions with added suffix (mpg123_open_64).
+	Any mismatch will be caught at link time because of the _FILE_OFFSET_BITS setting used when
+	building libmpg123. Plus, there's dual mode large file support in mpg123 since 1.12 now.
+	Link failure is not the expected outcome of any half-sane usage anymore.
+
+	More complication: What about client code defining _LARGEFILE64_SOURCE? It might want direct access to the _64 functions, along with the ones without suffix. Well, that's possible now via defining MPG123_NO_LARGENAME and MPG123_LARGESUFFIX, respectively, for disabling or enforcing the suffix names.
+*/
+
+/*
+	Now, the renaming of large file aware functions.
+	By default, it appends underscore _FILE_OFFSET_BITS (so, mpg123_seek_64 for mpg123_seek), if _FILE_OFFSET_BITS is defined. You can force a different suffix via MPG123_LARGESUFFIX (that must include the underscore), or you can just disable the whole mess by defining MPG123_NO_LARGENAME.
