Windows tweaks

[IngwiePhoenix]

I wanted to fool around with this for a while, so I made adjustments to make this work on Windows.

To reproduce:

• Install Chocolatey
• choco install visualstudio2019community
• choco install visualstudio2019buildtools visualstudio2019-workload-nativedesktop
• choco install winflexbison3 make

Add this makefile: Makefile.win32

splash: lexycal syntax compile
        @echo DONE

lexycal:
        win_flex.exe --wincompat -o compiler/lex.yy.c compiler/splash.lm
syntax:
        win_bison.exe -d compiler/splash.ym -o compiler/splash.tab.c

compile:
        cl.exe /nologo compiler\structures/*.c compiler\scope.c compiler\action.c compiler\output.c compiler\utils.c compiler\splash_helper.c compiler\interpolated.c compiler\lex.yy.c compiler\splash.tab.c compiler\main.c /Fe:splash

# Not implemented properly...
.PHONY : clean
clean:
        @rm \
                compiler/splash.tab.c \
                compiler/lex.yy.c \
                compiler/y.tab.c \
                splash \
                2> /dev/null || :

And apply this patch:

Then: make -f Makefile.win32 splash Et voila, there is a splash.exe :) ... and a crapload of .obj files. I didn't go all the way to not make these go into temporary folders or something. Anyway, this got a seemingly working binary. Compiling the age example seemed to work - now all that is left is to make it run on my phone ^^

Enjoy!
