First I began with compiling slang:

---------------------------------X------------------------------------
Setting up environment for MinGW-w64 GCC 64-bit...

Now run mingw32-make to build the library.  But first, you should
 look at Makefile and change the installation locations if
 necessary.

That was just OK, but when I try to do the make, it fails. Before doing
this I edit the .\src\Makefile like the following:

prefix=/mingw/local #in this line
prefix=/mingw64/local #I made this change

Now I try the make:

---------------------------------X------------------------------------
C:\Sources\s-lang>mingw32-make
cd src && mingw32-make COPY="cmd /c copy /y" RM=del
prefix=C:/mingw/local

The Compiler mingw64 don't know this "HANDLE" in line 1403 in the
.\src\slang.h. Also there is an error belonging to the slang.c.

With those errors there isn't generated a .\gw32objs\slang.o and so this
file ist missing for the following actions.

I think too, thanks.
Because in the generated Makefile you can see:

 | # This Makefile is for the MINGW32 environment

This is logical.

I don't know.
But in the mingw64-manual there is described, that with the right
configuration automatically is choosed the 64-Bit variant of mingw64. In
its subdirectory there are both plattforms 32-bit and 64-bit.
I have configured for to use the 64-bit plattform for mingw64.
The commands are "mingw32" at all, used is just 64-bit.
