The sdl-config sh-script doesn't work that well under windows. Would it be an idea to include a cmd-script?

If created a port of the script. Here's the source:

@echo off
set VAR=before
if "!VAR!" == "before" (
    set VAR=after
    if not "!VAR!" == "after" (
		cmd /V:ON /C %0 %1 %2 %3 %4 %5 %6 %7 %8 %9
		exit /B
	)
)

set prefix=c:/mingw/bin
set exec_prefix=%prefix%
set exec_prefix_set=no

set usage=Usage: sdl-config [--prefix[=DIR]] [--exec-prefix[=DIR]] [--version] [--cflags] [--libs] [--static-libs]

if "%1"=="" (
    echo !usage! 1>&2
	exit /B
)

set L=%1,%2,%3,%4,%5,%6,%7,%8,%9
for %%f in (!L!) do (
  set G=%%f
  set Q=!G:~0,9!
  if "!Q!"=="--prefix=" (
	set prefix=!G:~9!
	if !exec_prefix_set!==no (
	  set exec_prefix=!G:~9!
	)
  )
  set Q=!F:~0,14!
  if "!Q!"=="--exec-prefix=" (
	set exec_prefix_set==yes
    set exec_prefix=!G:~14!
  )
  if "!G!"=="--prefix" (
    echo !prefix!
  )
  if "!G!"=="--exec-prefix" (
    echo !exec_prefix!
  )
  if "!G!"=="--version" (
    echo 1.2.13
  )
  if "!G!"=="--cflags" (
    echo -I!prefix!/include/SDL -D_GNU_SOURCE=1 -Dmain=SDL_main
  )
  if "!G!"=="--libs" (
    echo -L!exec_prefix!/lib  -lmingw32 -lSDLmain -lSDL  -mwindows
  )
  if "!G!"=="--static-libs" (
    echo -L!exec_prefix!/lib  -lmingw32 -lSDLmain -lSDL  -mwindows
  )
)
