Компиляция программ на основе SDL 0

Возьми мой :-) Поставь свой префикс только

#!/bin/sh
prefix=/usr
exec_prefix=${prefix}
exec_prefix_set=no
usage="\
Usage: sdl-config [--prefix[=DIR]] [--exec-prefix[=DIR]] [--version] [--cflags] [--libs] [--static-libs]"
if test $# -eq 0; then
      echo "${usage}" 1>&2
      exit 1
fi
while test $# -gt 0; do
  case "$1" in
  -*=*) optarg=`echo "$1" | sed 's/[-_a-zA-Z0-9]*=//'` ;;

  esac
  case $1 in
    --prefix=*)
      prefix=$optarg
