warning: Negative offset for 'variable'

Hi!
 
What does the warning "Negative offset for 'variable'" mean? "variable" is the name of a global static data variable.
 
Thanks,

In one of the compiler release notes this is mentioned that this warning appears "too often."
 
What i noted was I had declared storage for a global array.  In the header module, I declared this as "extern" and duplicated the array size.  This did some odd things - seems it did not properly allocate the storage and was overridden by something else (my guess).
 
What I did to fix it was removed the size of the array in the header file so it just said, "extern int variable[]" while the global declaration said, "int variable[14]".
