redefinition error with loops

[ElectroLund]

In some of my CVI projects, I get the following error:

error: redefinition of 'i'

This is for two loops that have the same local variable name, both inside a function call like this:

fdsdfdsfda

function(void)
{
  for (int i=0; i<1000; i++)
  {
  }
	
  for (int i=0; i<10000; i++)
  {
  }
}
	

Now here's the catch!  This same code is identical in other CVI projects, where I don't get that error.  Seems like a Build Options issue, right?  But I can't find a difference between the two projects.
