Revert "Fix gcc-4.8 compilation warning when using -Wstrict-overflow"

Browse Source 
This reverts commit 79109a8546f963d17522d75112cffcfd8cbe35fc.

This warning does not happen on gcc-4.8.4; the workaround introduces an
unsigned integer overflow which results in a runtime error when compiled
with integer sanitizer.
