Thanks for forwarding these warnings. They arise because I'm using
'signed int' or 'unsigned int' as a base type for a bit field. This
was not allowed in C90 (ANSI C), but is allowed in ISO C 99 (see paragraph
6.7.2.1.(4)). The effect of the warning is that the 'signed' / 'unsigned'
attribute gets stripped, which - for unsigned - reduces the available
effective width by 1 bit. I have verified that it is no problem in this
case.
