-*******
-
-There was some support in LibreOffice already from OpenOffice.org days
-for building it locally on Windows with the GNU tool-chain (MinGW).
-Apparently, those doing that work never attempted cross-compilation.
-
-This OOo-originated MinGW support attempts to be for both running the
-Cygwin gcc in its -mno-cygwin mode, and a Windows-native MinGW
-compiler. The -mno-cygwin mechanism in the Cygwin gcc is rapidly being
-obsoleted, if it isn't already, and we have not attempted to try to
-keep it working; in fact we have actively cleaned out mechanisms
-related to this. Ditto for native MinGW. If one compiles natively on
-Windows, just use a version of Microsoft's compiler. OpenOffice.org
-and LibreOffice have been built for Windows all the time using that.
-
-The only case where it makes sense to use MinGW is for
-cross-compilation. There is just too much crack involved on Windows
-anyway, and it is a semi-miracle that the MSVC build under Cygwin
-works as nicely as it does.
-
-MinGW is available as cross-build toolchains pre-packaged in more or
-less official packages for many Linux distros including Debian, Fedora
-and openSUSE. For instance, the mingw32 packages in the Open Build
-Service, running on openSUSE, can be found at:
-
-http://download.opensuse.org/repositories/windows:/mingw:/win32/
-
-For example, you can install it like this:
-
-zypper ar http://download.opensuse.org/repositories/windows:/mingw:/win32/<your_os>/windows:mingw:win32.repo
-
-where <your_os> is one of SLE_11, SLE_11_SP1, openSUSE_XX.Y, or
-openSUSE_Factory.

-
-zypper in wine wine-devel wine-devel-32bit
-
-And in order to be able to use 'winegcc -m32', also
-
-zypper in glibc-devel-32bit gcc-32bit
-
-There might be more that are missing, please read carefully what autogen.sh
-tells you, and either remove one of the --with-system-*, or install the
-missing dependency.
-
-It also looks like graphite2.pc needs tweaking in order to work right; but
-that's likely to be fixed in the openSUSE project.
-
-It is somewhat unclear how well thought-out the conditionals and code
-for MinGW inside the OOo-originated code in LibreOffice actually
-are. It often seems a bit randomish, with copy-pasting having been
-preferred to factoring out differences.
-
-Most of the configuration settings are maintained in the
-distro-configs/LibreOfficeMinGW.conf file, so in your autogen.input,
-you can use:
-
-CC=ccache i686-w64-mingw32-gcc
-CXX=ccache i686-w64-mingw32-g++
-CC_FOR_BUILD=ccache gcc
-CXX_FOR_BUILD=ccache g++
---with-distro=LibreOfficeMinGW
-
-Alternatively, you can use something like the following; but the
-preferred way is to keep the LibreOfficeMinGW.conf file up-to-date.
-
-CC=ccache i686-w64-mingw32-gcc
-CXX=ccache i686-w64-mingw32-g++

-Once you have compiled it, you may want to try to run it, for instance
-using Wine:
-
-$ cd /tmp
-$ tar xf <your-build-dir>/workdir/wntgcci.pro/installation/LibreOffice_Dev/archive/install/en-US/LibO-Dev_4.1.0.0.alpha0_Win_x86_archive.tar.gz
-$ cd LibO-Dev_4.1.0.0.alpha0_Win_x86_archive/LOdev\ 4.1/program/
-$ wine soffice.exe
-
-NB. it is important to unpack somewhere low in the hierarchy structure (like
-in /tmp as advised above), otherwise you'll get BerkeleyDB errors on startup.
-
-And if you are brave enough, you can even debug it.  First you have to add the
-URE dll's to the wine's PATH using 'wine regedit' - see
-http://www.winehq.org/docs/wineusr-guide/environment-variables, and add
-Z:\tmp\LibO-Dev_4.1.0.0.alpha0_Win_x86_archive/LOdev\ 4.1\URE\bin
-to "Path" in My Computer->HKEY_CURRENT_USER->Environment.
-
-And start debugging:
-
-$ winedbg soffice.bin
-
-Would be great to be able to use winedbg --gdb, but it was crashing here :-( -
-but maybe you'll be more lucky.
-
-Tricks of some use with winedbg:
---------------------------------
-
-To examine OUStrings, you might want to use the following trick (prints 50
-unicode characters of rLibName OUString - the +10 is where the buffer starts):
-
-Wine-dbg>x /50u rLibName->pData+10
-0x0909b6c8: vnd.sun.star.expand:$LO_LIB_DIR/abplo.dll
-
-TODO:
-
-- make the debugging more convenient on (native) Windows
-  - check possibilities like WinGDB - http://www.wingdb.com/
-  - or find / write a MSVS / WinDBG extension that can read MinGW debugging
-    symbols natively; more info
-    http://windbg.info/forum/12-symbol-and-source-files-/21-debugging-mingwgcc-built-dll-in-visual-studio.html
-
-- installation
-  - so far the make_installer.pl calls makecab.exe, uuidgen.exe, and
-    others; would be best to avoid that if at all possible (using a free
-    cab implementation, part of Wine or something)
-  - MSI generation
-
-- runtime
-  - no idea if the entire thing works after the installation at all; I
-    suppose there will be runtime problems to look at too
-
-- cleanup
-  - enable & fix pieces that are currently disabled
-    - --without-myspell-dicts
-    - --disable-directx
-    - --disable-activex
-  - much of the stuff currently relies on --with-system-*, and
-    consequently on the mingw32-* openSUSE packages; might be good to be
-    able to build with as few dependencies as possible - but that is low
-    prio
-
-- profiling
-  - when all the above is sorted out, we should look at the speed of
-    this vs. the speed of the MSVC version
