+	* builds/unix/configure.raw: Remove `SYSTEM_BZ2LIB' macro.
+
+	SYSTEM_ZLIB is used to switch the builtin zlib source
+	or system zlib source out of FreeType2.  But ftbzip2
+	module has no builtin bzip2 library and always requires
+	system bzip2 library.  Thus SYSTEM_BZ2LIB is always yes,
+	it is not used.
