Thanks Dave
Seems to be working fine here.
Do you see that "Amoebax" is also compilable? It uses also zlib , libpng, Ogg, Vorbis

I'll try later.
Do you use automake for the ones that have "Makefile.am" ?
For OS/2, best to rebuild all the auto stuff. Often there is an autogen.sh that takes care of the rebuilding, otherwise autoreconf -sfi usually takes care of running the tools, aclocal, autoconf, automake, libtool, all with the right parameters.
autogen.sh for atris for example of a simple one,
#!/bin/sh
#
aclocal
automake --foreign
autoconf
./configure $*
Which actually failed due to missing compile file or such, so I ran autoreconf -sfi to install the scripts and afterwards if needed, ran autogen.sh. Reason for needing to fix was, IIRC, a macro that used #include <SDL.h> while newer SDL such as ours needs #include <SDL/SDL.h>. Source needed adjusting the same way.
Edit: add bottom section.
