-Wl,xxx is an instruction to gcc to pass xxx to the underlying linker
(ld). So gcc sees
   -Wl,-stack_size -Wl,0x4000000
and ld sees
   -stacksize 0x4000000

This is very likely MocOS-specific; here, 'man ld' says

      -stack_size value
              Specifies  the size of the stack segment value, where value is a
              hexadecimal  number  rounded  to  the  segment  alignment.   The
              default  segment  alignment  is  the target pagesize (currently,
              1000 hexadecimal for the PowerPC and for i386).  If  -stack_addr
              is  specified  and -stack_size is not, a default stack size spe-
              cific for the architecture being linked will  be  used  and  its
              value  printed  as  a  warning  message.  This creates a segment
              named __UNIXSTACK .
