Glad to see some other people taking a crack at it.  I just don't have
the time these days.  I never did much with my own builds except remove
the broken 'ver' command.

I still want to fix the instability with setting environment variables,
and add the BEGIN/ENDLIBPATH stuff in, but again, that takes time I
don't really have...

What I have here builds, although I get that warning too:

gcc -O2 -Wall -Zomf -c -o yaos.obj yaos.cc
yaos.cc: In function `void setTitle(char *)':
yaos.cc:30: warning: ANSI C++ forbids cast to non-reference type used as lvalue
gcc -O2 -Wall -Zomf -c -o util.obj util.cc
gcc -O2 -Wall -Zomf -c -o ycd.obj ycd.cc
ycd.cc:55: warning: `#ifdef' argument starts with a digit
ycd.cc:143: warning: `#ifdef' argument starts with a digit
gcc -O2 -Wall -Zomf -c -o ext.obj ext.cc
gcc -O2 -Wall -Zomf -c -o file.obj file.cc
gcc -O2 -Wall -Zomf -o yaosa.exe yaos.obj util.obj ycd.obj ext.obj file.obj 
-lvideo yaos.def

I left the -Zomf in and it works OK.  Also using GCC 2.8.1.

I did have to change my CPLUS_INCLUDE_PATH to put e:\emx\include before
e:\emx\include\cpp (otherwise getopt breaks).

Various EMX-related paths I have:
CPLUS_INCLUDE_PATH=e:/emx/include;e:/emx/include/cpp;e:/usr/include;e:/usr/loca
l/include;
LIBRARY_PATH=e:/emx/lib;e:/usr/lib;e:/usr/local/lib
C_INCLUDE_PATH=e:/emx/include;e:/usr/include;e:/usr/local/include;e:/usr/local/
include/ncurses;
OBJC_INCLUDE_PATH=e:/emx/include;e:/usr/include;e:/usr/local/include
PROTODIR=e:/emx/include/cpp/gen
