Gas is complaining about a missing `*'. You should write
call *sys_call_table(,%eax,4)
to be strictly legal. It's one of those quirks of AT&T assembler that
absolute jumps and calls have a '*' while pc relative jump and calls
don't. You really only need the '*' to distinguish between them in the
case where no register or base/index expression is given. eg. `jmp foo'
vs. `jmp *foo' However, the syntax does make quite a lot of sense.
`jmp foo' branches to the label `foo', while `jmp *foo' reads the
destination address from the memory location foo, then jumps there. Think
of the `*' as being a pointer operation.
