Cross compilation of ja2 on Ubuntu 14.04

[ooxi]

I wanted to help debugging issue #146 and tried cross compiling ja2 on Ubuntu 14.04 using the compilation instructions. I ran into a couple of difficulties which resulted in the following pull requests

• Pull Request #12, SDL has to be installed
• Pull Request #13, mingw does not like the UTF-8 BOM. Remove it since it's unneccessary
• Pull Request #14, __min and __max are MSVC dependend therefore I changed all invocations to MIN/`MAX
• Pull Request #15, made definition of MIN/MAX platform idependend

Now everything compiles fine but the linker tells me

/usr/lib/gcc/i586-mingw32msvc/4.2.1-sjlj/../../../../i586-mingw32msvc/bin/ld: cannot find -lpthread

I don't know which package is neccessary to fix this :(

Instructions are not corrent. It should be:

  Ubuntu 12.04 i386:
    $ sudo apt-get install gcc-mingw32
    $ make clean
    $ make USE_MINGW=1 MINGW_PREFIX=i586-mingw32msvc LOCAL_SDL_LIB=_build/lib-SDL-devel-1.2.15-mingw32 WITH_LPTHREAD=0

  Ubuntu 12.04 x64:
    $ sudo apt-get install gcc-mingw-w64 g++-mingw-w64
    $ make clean
    $ make USE_MINGW=1 MINGW_PREFIX=i686-w64-mingw32 LOCAL_SDL_LIB=_build/lib-SDL-devel-1.2.15-mingw32 WITH_LPTHREAD=0

For Ubuntu 14.04 x64 instructions are the same as for 12.04 x64. I haven't checked 32bit system, but probably the same as for 12.04 also.

Thank you for discovering this issue and trying to fix it.

Thank's for the fast reaction, it seams that I was a bit over ambitoned with my pull requests.

Could we create some integration tests, perhaps using Travis CI, in order to catch such issues? Looking at the issue historie there are quite a lot requests having the same problem :)
