+	Improve configure.raw to copy some options from CFLAGS to LDFLAGS.
+	The linker of Mac OS X 10.6 is sensitive the architechture.
+	When the architechtures are specified explicitly for C compiler,
+	the linker requires the architechture specifications too.
+
+	* builds/unix/configure.raw: Replace `-isysroot' option parser
+	by more generic argument parser.
