+Work-in-progress. Ignore for now.\r
+\r
+Some build scripts for GCC toolchains. Notably the\r
+Cortex CPUs require the very latest GCC version 4.3.x.\r
+\r
+These are to be considered working notes for testers and\r
+not a definitive source on how to build GCC toolchains.\r
+\r
+1. get latest binutils, gcc, gdb and newlib\r
+\r
+2. unzip source to src folder\r
+\r
+2. fix libstc++/configure.ac\r
+\r
+\r
+That works. After replacing AC_LIBTOOL_DLOPEN with\r
+\r
+  if test "x${with_newlib}" != "xyes"; then\r
+    AC_LIBTOOL_DLOPEN\r
+  fi\r
+\r
+and running autoconf I was able to build six different newlib targets.\r
+\r
+http://gcc.gnu.org/ml/gcc/2008-03/msg00611.html\r
+\r
+3. place newlib and libgloss into src/gcc\r
+\r
+4. run cygwin.sh or linux.sh\r
