Install compiler tools:
- Go to http://www.msys2.org/
- Download and run msys2-i686-20180531.exe
- Start an msys mingw64 32-bit shell and type:
	pacman -S mingw-w64-i686-gcc 
	pacman -S mingw-w64-i686-make
	pacman -S mingw-w64-i686-pkg-config
	pacman -S mingw-w64-i686-vala
	pacman -S mingw-w64-i686-SDL_image
	pacman -S mingw-w64-i686-SDL_mixer
- Add c:\msys32\mingw64\bin to path
	
Install PERL:
- http://strawberryperl.com/releases.html
- Download portable 32 bit edition
- Extract to C:\perl
- Add C:\perl\perl\bin to path.

Download and extract CrossFire source to e.g. c:\cf.
- https://sourceforge.net/projects/crossfire/files/crossfire-client/

Install CMake:
- https://cmake.org/download/ - cmake-3.13.3-win64-x64.msi

Run CMake:
- Set source code directory, e.g. c:/cf
- Set binary directory, e.g. c:/cf/build
- Click 'Configure' and choose 'MinGW Makefiles'
- Change CMAKE_INSTALL_PREFIX to something reasonable
	- (C:/Program Files (x86)/... is probably read only).
- If CMake finds wrong include directories, e.g. from Visual Studio, change them manually to 'C:\msys32\mingw32\include'
- Click 'generate'.

- If configuring goes wrong, delete directory c:/cf/build/CMakeFiles and try again.

Compile:
- Open msys32 32-bit shell
- Go to c:/cf/build
- Run 'mingw32-make'

Create release package:
- Run 'mingw32-make install', though it doesn't seem to do much.
- Make directory 'release'
- Copy bin/*.exe to release/.
- Copy directory 'share' to release/.
- Copy directory 'lib' from the CF 1.72.0 distribution to release/. (Is this needed? Why?)

- Find the DLLs:
	- Most of the DLLs can be found in c:/msys32/bin.
	- Find the rest of the DLLs from the 1.72.0 release.
	- Find any missing DLLs from official runtime distributions.
	- If DLLs are still missing, shed some tears.
	- I had to rename libpng16_16.dll to libpng14_14.dll. I have no idea what could have required libpng14, and libpng14 has serious vulnerabilities too. (Renaming DLLs is not safe either.)
