The comma suggests (I think) that it is C90 that mandates that all one's
variables are declared at the top of the function.  But that's not the
case (as I am sure you know).  The other reading -- that this is done in
idiomatic C90 code -- is also something that I'd question, but not
something that I'd want to argue.

I comment just because there seems to be a myth that "old C" had to have
all the declarations at the top of a function.  That was true once, but
so long ago as to be irrelevant.  Even K&R C allowed declarations at the
top of a compound statement.
