It likes it just fine. You just need to build as C99 (or GNU99).

Jonathon,
GCC does not like declaring variables in a for statement. If you want to make
the variable m have the scope for only the for loop, you would need:
foo()
{
...
{
int i, m;
for (i=0, m=0; i5; i++){...}
printf(Final value of

Adding -std=c99 or -std=gnu99 to the compiler flags will fix that.

I can't chance upon the right incantation for using both an existing
variable and an inline new one in a for loop. I've boiled this down to
a trivial show case, same results for both gcc 4.0.1 and 4.2.1:
int i;
. . .
for (i=0, int m=0; i5; i++) { . . . };
printf(Final value of i:
I believe this is actually independent of being in a for loop. Your first
line corresponds to code like this:
int i;
i=0, int m=0;
Which is syntactically incorrect.
Your second example corresponds to this:
int i;
int m=0, i;
Which is an attempt to re-declare i.
So you're correct; you can't
