+= Building with MingW64 w64, w32 chains =
+== 1. Installing Minimalist GNU for Windows-w64 (MinGW-w64) ==
+The mingw64 for build 32-bit binaries only works for PostgreSQL 9.2+.  There are changes they did in 9.2 that were never backported to 9.1 and below. So to compile PostGIS for 32-bit for 9.1 and below you need to use the regular old Msys instructions. mingw64 chain will work for 64-bit 9.0-9.3 and for 32-bit 9.2-9.3.
+
+We will use MingGW-w64 toolchain instead of the standard MingW since it has support for both 32-bit and 64-bit compiling.
+For this discussion we are using the binaries built for running on Windows. We haven't tried the builds designed for building windows binaries under ''Linux/Unix''.
+
+Details of the prefixes of files can be found at [http://sourceforge.net/apps/trac/mingw-w64/wiki/download%20filename%20structure What to download]
+
+MingW-w64 site is [http://mingw-w64.sourceforge.net] 
+There are issues with GEOS compile above 4.5.4 or so, in 4.6.1+, the make check crashes and so does
+PostGIS tests when compiled with GCC 4.6+.  That said you should pick a build lower than GCC 4.6. We like GCC 4.5.4
+Issues are documented in http://trac.osgeo.org/geos/ticket/518 (also similar issue compiling Geos under windows 64-bit SDK http://trac.osgeo.org/geos/ticket/528 )
+
+ * If you are building for 64-bit Windows download the personal build from [http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/sezero_4.5_20111101/] with name
+starting with '''mingw-w64-bin_x86_64-mingw_20111101_sezero.zip'''
+
+ * If you are building for 32-bit Windows download one of the binary packages from [http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/sezero_4.5_20111101/] with name starting with
+'''mingw-w32-bin_i686-mingw_20111101_sezero.zip''' 
+
+ * Extract your respective zip into a folder called C:\ming64\mingw64 or c:\ming32\mingw32
+ * Download the latest patch in same folder e.g. sezero_20111101-w32-update-rev.5151.zip for win32, sezero_20111101-w64-update-rev.5151.zip for win64 and extract into same respective folders. There might be a newer patch use that one.

+/** NOTE to self: This may not be necessary anymore **/
+GEOS fails to link if it picks up 32-bit dlls so to overcome this, I copied over the dlls from windows/sytem32 and renamed them as
+described in 
+#linking errors seems to be caused by as described here [http://www.gaia-gis.it/spatialite-3.0.0-BETA/mingw64_how_to.html#env]
+mingw64 is picking up the 32-bit dlls from syswow64 instead of the 64-bit dlls from windows/system32
+I only needed to copy ws2_32.dll for geos to compile without errors
+Others may be needed not sure.
+with windows explorer copy the files from windows/system32
+
+{{{
+ws2_32.dll
+}}}
+
+To your folder: C:\ming64\x86_64-w64-mingw32\lib
+and then rename them adding a lib extensions so you have
+{{{
+libws2_32.dll
+# these ones didn't seem necessary for PostGIS: libmsimg32.dll,libgdi32.dll, libcrypt32.dll and libwldap32.dll
+}}}
+
+
+== prefixed files ==
+These sometimes exist only with the prefixes and cause issues during compilation so you'll need prefixless versions
+
+{{{
+cp /mingw/bin/x86_64-w64-mingw32-cpp.exe /mingw/bin/cpp.exe
+cp /mingw/bin/x86_64-w64-mingw32-strip.exe /mingw/bin/strip.exe
+}}}
+
+== 2. Installing Msys ==
+
+MSys is 32-bit but you can use it with your 32-bit or 64-bit mingw-w64.  Instructions are here [http://sourceforge.net/apps/trac/mingw-w64/wiki/MSYS mingw-w64 with MSYS] and repeated
+here for completeness
+
+ *  download [http://sourceforge.net/projects/mingw-w64/files/External%20binary%20packages%20%28Win64%20hosted%29/MSYS%20%2832-bit%29/ Msys] MSYS-20110309.zip (update there is now a newer MSYS -- MSYS-20110526.zip)
+ * Extract into a folder called C:\Ming64\msys (or C:\Ming32\msys)
+ * launch msys.bat
+ * type
+
+{{{
+sh /postinstall/pi.sh
+}}}
+
+When prompted type in 
+{{{C:/ming64/mingw64}}} or {{{C:/ming32/mingw32}}}  depending on which tool chain you chose
+Once done, type logout and the console should exit.
+Note: You can have both if you are using windows 64-bit and we do.
+
+GEOS also gives missing vtable message during link.  I think this was caused by msys missing find.exe, so I copied the find.exe from regular msys package ( as instructed in the [http://www.gaia-gis.it/spatialite-3.0.0-BETA/mingw64_how_to.html#env] to bin of respective ming64/ming32 msys folders.
+
+== 3a. Installing Autoconf, Automake and Libtool ==
+Relaunch C:\ming64\msys\msys.bat (or c:\ming32\msys\msys.bat)
+
+
+
+
+We create a file with commands like this 
+and make sure this is included in all my compile scripts
+
+{{{
+#if you are building for 32-bit change ming64 to ming32
+export PROJECTS=/c/ming64/projects
+#for a 64-bit build
+export MINGHOST=x86_64-w64-mingw32
+#if you are building for 32-bit change to this
+#export MINGHOST=i686-w64-mingw32 
+
+#this part is not necessary
+#but we like to prefix our binary folders with
+#version
+export OS_BUILD=64 #change to 32 if building for 32
+}}}
+
+{{{
+#if you are building for 32-bit change ming64 to ming32
+mkdir ${PROJECTS} 
+}}}
+
+
+Verify which versions of these you have with
+
+autoconf --version 
+
+etc.
+
+If they are not newer (or you get not found) than below then download and install.
+Download the source code from the GNU site and save to c:\projects
+
+ * http://ftp.gnu.org/gnu/autoconf/autoconf-2.65.tar.gz
+ * http://ftp.gnu.org/gnu/automake/automake-1.11.1.tar.gz
+ * http://ftp.gnu.org/gnu/libtool/libtool-2.4.tar.gz
+
+
+{{{
+
+cd ${PROJECTS}
+tar -xvf autoconf-2.65.tar.gz
+cd autoconf-2.65
+./configure --host=${MINGHOST} --prefix=/mingw  (if you are building for 32-bit then use --host=i686-w64-mingw32)
+make && make install
+autoconf --version
+}}}
+
+repeat same exercise for automake
+
+For libtool
+{{{ 
+cd ${PROJECTS}
+tar -xvf libtool-2.4.10.tar.gz 
+
+cd libtool-2.4.10
+./configure --host=${MINGHOST} --disable-shared --prefix=/mingw
+#if you get a message that gcc is not usable, then you probably set your
+# mingw setting wrong or did not install automake/autotools in /mingw
+#try to fix by rerunning the sh /postinstall/pi.sh again
+make clean && make && make install
+libtool --version
+
+}}}
