Header file problems

[James Brown-24]

Hi mspgcc,

I am currently using the windows install of mspgcc version 20081230.  I
am using an MSP430F233 device and I have noticed a couple of issues with
the MSPGCC header files included from <io.h>

Firstly in the file msp430x23x.h (version 1.1) it does not include
<msp430/adc12.h> which is required for the on chip 12 bit ADC.  I
checked the CVS repository to see if this had been fixed but I could not
find the file.

Secondly in the file msp430/iostructures.h (version 1.11) there seems to
be some sort of packing issue with the type ioregister_t.  It seems to
generate incorrect offsets because the size of ioregister is 2 and not 1
as it should be.  I got around the problem by redefining ioregisters_t
as

typedef union port {
  __VOLATILE __MSP430_UNS__ char reg_p;
  __VOLATILE struct {
    __MSP430_UNS__ char __p0:1,
      __p1:1,
      __p2:1,
      __p3:1,
      __p4:1,
      __p5:1,
      __p6:1,
      __p7:1;
  } __attribute__ ((packed)) __pin;
} __attribute__ ((packed)) ioregister_t;

I have added the "__attribute__ ((packed))" to the __pin member.  Not to
sure if this was the best way to go about this but it worked.

Has anyone else come across these issues?

Regards,
James Brown
