Can't do this.  A segment register can only be the destination of a
 move from a general purpose register (ax, bx, cx, dx) or it can be the 
destination of a pop instruction.

Can't do this either.  You have a 32 bit register as the destination 
of a 16 bit move.

In the future, you can find the exact line of the problem by 
compiling with -S and redirecting the output to a file, the run gcc 
on that file.  For example:

gcc -S foo.c > bar.s
gcc bar.s
