 I am porting some code from a 32 bit machine (IBM PC/RT running AIX) to
 a 16 bit machine (IBM PC/AT running DOS and OS/2) and I have come
 across a problem with the size of bit fields.  It seems bit fields
 longer than 16 bits are not supported on 16 bit machines.  I was
 wondering what one does to port this code in a situation such as this?

 Would it be possible to change the bit fields to long int's?
 For example:


		int i:28;
	to
		long i;

I don't care about the extra memory it would take up, but I am
concerned about differences in referencing bits in a variable vs. 
referencing bits in a bit field.
