"Upgrade 2012 DOS MPlayer to Version 1.5"

Hi,
Using the following Hotlinks as a baseline:

Are there any savvy DJGPP coders able to upgrade DOS 2012 mplayer to its present version 1.5, using the following DJGPP cross compiler GCC version 12.2.0 build script from:

#!/usr/bin/env bash

# Path to DJGPP cross compiler
export DJGPP_PREFIX="/Users/owner/djcc"
export PATH="$DJGPP_PREFIX/bin:$PATH"

# Your cross compilation target
TARGET_ARCH="$DJGPP_PREFIX/bin/i586-pc-msdosdjgpp"

# Download MPlayer source code
MPLAYER_VERSION="1.5"
MPLAYER_ARCHIVE="http://www.mplayerhq.hu/MPlayer/releases/MPlayer-${MPLAYER_VERSION}.tar.xz"
MPLAYER_SOURCE_DIR="MPlayer-${MPLAYER_VERSION}"

# Download MPlayer source
echo "Downloading MPlayer source..."
wget -c "$MPLAYER_ARCHIVE" || exit 1
tar -xf "MPlayer-${MPLAYER_VERSION}.tar.xz" || exit 1
cd "$MPLAYER_SOURCE_DIR" || exit 1

Hi,
After configuring mplayer 1.5 for cross compilation, its gcc 12.2.0 compile stumbled on this common alignment issue:

Are there any proposed upgrade to this issue?
