It should be +=, but it won't affect anything. These flopcounts are only
used if you enable all the comments when building the inner loops, and 
in that case we will ge a report of the number of flops used in each 
inner loop (so we can enter it in src/gmxlib/nrnb.c to get the right
flopcount).

Cheers,

Erik
