The first construct, declaring the int variable i within the for loop, is 
only legal in C++ not in C.  So take a careful look at each of your 
'sometime's and you should see that it works in .cc files and in .c files 
which you have asked gcc to compile as C++ explicitely but not in normal 
C compiles.
