gcc7 patch

[Jason Bacon <outpaddling%yahoo.com@localhost>]

After fixing binutils, gcc7 also fails on CentOS 7.

The simple patch below fixes the issue, which is clearly flagged by 
error messages stating that variable definitions in for loops are only 
supported in C99 mode.

Any concerns about this patch?

Thanks,

    JB
