+# It has been used to build cross compilers from Linux to Cygwin,
+# MinGW, and SunOS.  It is unlikely that this script will work
 # out-of-the-box.  It is only intended as a template.  You should read
 # through it and understand what it does, and make changes as
 # necessary.  Feel free to add another targetType if you modify this
 # script for another target.
 
+# Notes from Anoq about the mingw target:
+# I downloaded the following files from www.mingw.org:
+# *) binutils-2.13.90-20030111-1-src.tar.gz which I unpacked to
+#    binutils-2.13.90-20030111-1-src.tar
+#    This script unpacks the .tar to binutils-2.13.90-20030111-1-src
+# *) gcc-3.2.3-20030504-1-src.tar.gz which I unpacked to
+#    gcc-3.2.3-20030504-1-src.tar
+#    This script unpacks the .tar to gcc-3.2.3-20030504-1
+# However when running make on gcc it complains about missing files
+# stdlib.h and unistd.h
