+Subject: [PATCH] Fix error when building with uClibc-ng
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The uClibc-ng C library defines a type called R0 that conflits with a
+global variable called R0 from PaddleReader.cxx.
+
+src/emucore/tia/PaddleReader.cxx:25:3: error: ?constexpr const double R0? redeclared as different kind of symbol
+   R0 = 1.5e3,
+   ^
+/home/sprado/workspace/build/buildroot/build/stella_uclibc/host/arm-buildroot-linux-uclibcgnueabi/sysroot/usr/include/sys/ucontext.h:42:3: note: previous declaration ?<anonymous enum> R0?
+   R0 = 0,
+   ^~
+
+So let's redefine R0 as a private member of the PaddleReader class.
