I had great difficulties to compile this code (example):

void main()
{
	for (int i=0; i<100; i++);
}

All I got was errors, i not initialized it said.
I tried to move it out to...

void main()
{
	int i;
	for (i=0; i<100; i++);
}

....but all the same.

It only worked when I (at last) put the i globally.

int i;
void main()
{
	for (i=0; i<100; i++);
}

Interesting.  I tried the following code with DJGPP V2 and it worked:
	int	main()
	{
		int	i;
		
		for (i = 0; i < 100; i++);

		return 0;
	}

Also, when using C++, the following code worked, as expected:
	int	main()
	{
		for (int i = 0; i < 100; i++);

		return 0;
	}

What makes DJGPP unable to use local variables in for() and asm("") ?
Someone?
You can declare variables as static and use them in an asm() construct.
