There are a few other uses of some of these XXX_time variables which you've missed.

parse_time and varconst_time are used in gcc/cp/decl2.c and declared as "extern int"
gc-time is used in gcc/gc_page.c and gc_simple.c and declared as "extern int".

All the other XXXX_time variables are only accessed in toplev.c

I think parse_time, varconst_time, and gc_time should be defined in toplev.h and
all the other XXXX_time variables become static.
