using bitfield syntax

[Junior <ejr@inbox.com>]

Does anyone know if bit fileds can apply to 16 or 32 for ARM9 without any prolems?
I've always used 8 bits, that is to say
struct bitfileds
{
   unsigned bit0: 1;
   unsigned bit1: 1;
   ...
   unsigned bit7: 1;
};

instead of
struct bitfields
{
   unsigned bit0: 1;
   ...
   unsigned bit15: 1;
}

Would I have any possible problems with the latter? I don't see why and I don't have any reason to think it would cause problems.

Thanks
