 ### Compiler speed switches for both GCC and ICC. These settings are generally
 ### fast on a broad range of systems, but may be changed experimentally

-### NOTE: Some versions of gcc miscompile value.h with -O2 or -O3, this is the
-### safe setup, try changing to -O3 or -O2 and verify it works for you.
