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