GAS uses AT&T syntax.  it differ from Intel syntax which TASM/MASM uses.
reading Assembly HOWTO might help you a bit.

there is a program which can convert AT&T syntax <-> Intel's.
try freshmeat.net.

i haven't tried linking objct file from any asembler other than 
gas with gcc, but there should be a way to do it.

seems to me that your gcc isn't EGCS/PGCC.  try

% gcc -v

i think only pgcc knows optimize level higher than 7.
egcs/pgcc and gcc 2.8 or higher knows 586 or higher -m option

that says, your gcc is gcc 2.7.x, isn't it?

Lynx!!
i haven't work on lynx, so i don't know everything i wrote
is valid under Lynx.
