+/* Timing variables are used to measure elapsed time in various
+ portions of the compiler. Each measures elapsed user, system, and
+ wall-clock time, as appropriate to and supported by the host
+ system.
+
+ Timing variables are defined using the DEFTIMEVAR macro in
+ timevar.def. Each has an enumeral identifier, used when referring
+ to the timing variable in code, and a character string name.
+
+ Timing variables can be used in two ways:
+
+ - On the timing stack, using timevar_push and timevar_pop.
+ Timing variables may be pushed onto the stack; elapsed time is
+ attributed to the topmost timing variable on the stack. When
+ another variable is pushed on, the previous topmost variable is
+ `paused' until the pushed variable is popped back off.
+
+ - As a standalone timer, using timevar_start and timevar_stop.
+ All time elapsed between the two calls is attributed to the
+ variable.

+/* This structure stores the various varieties of time that can be
