Hi Asim & Ludolf,
If sfrb, sfrw or indeed anything else non-standard is causing parse
problems for splint, you may find that you can usefully redefine them
via the splint -D command-line option. A few examples:

 -Dsfrb="" will tell splint's preprocessor to define sfrb to be the
empty string.

-Dsfrb="unsigned char" will tell splint to treat sfrb as an unsigned
character.

-Dsfrb'('w,x,y,z')'="" might be more appropriate if sfrb takes arguments

I'm not familiar with the IAR compiler, so I don't know if sfrb & sfrw
can safely be ignored by splint, or whether redefining them will "fool"
splint appropriately.

Bye,
Brian
