Maybe add a TODO to remove this enum altogether

 
 // Provide type for an alternate timer function.
 typedef unsigned int NowFunction();
 
-// Environment variable name that is used to activate alternate timer profiling
-// (such as using TCMalloc allocations to provide a pseudo-timer) for tasks
-// instead of wall clock profiling.
-BASE_EXPORT extern const char kAlternateProfilerTime[];
-
 // Set an alternate timer function to replace the OS time function when
 // profiling.  Typically this is called by an allocator that is providing a
 // function that indicates how much memory has been allocated on any given
