3.17.12 H8/300 Options
These `-m' options are defined for the H8/300 implementations:
     
-mrelax- Shorten some address references at link time, when possible; uses the
linker option -relax.  See 
ld and the H8/300, for a fuller description.
     
 -mh- Generate code for the H8/300H.
     
 -ms- Generate code for the H8S.
     
 -mn- Generate code for the H8S and H8/300H in the normal mode.  This switch
must be used either with -mh or -ms.
     
 -ms2600- Generate code for the H8S/2600.  This switch must be used with -ms.
     
 -mint32- Make 
int data 32 bits by default.
     
 -malign-300- On the H8/300H and H8S, use the same alignment rules as for the H8/300. 
The default for the H8/300H and H8S is to align longs and floats on 4
byte boundaries. 
-malign-300 causes them to be aligned on 2 byte boundaries. 
This option has no effect on the H8/300.
