If i compile the attached args.c, i get the following errror message in
mainline GCC.

In file included from args.c:2:0:
structdef.h:5:3: error: expected ‘:’, ‘,’, ‘;’, ‘}’ or ‘__attribute__’ before
‘unsigned’

Note that it says args.c:2:0. We used to use GCC 4.3.2, which used to only say
args.c:2. The extra ":0", which is supposed to represent column number, is just
wrong. In the attached test, the actual column number is "3". I am happy for
the compiler to not give any column number, but giving the wrong column number
looks wrong.

I saw this in picochip code, but i am guessing this is not specific to
picochip. Please let me know if you need any more information. Thanks
