described by the sprofil(2) man page of Irix v6.5, except that:
- there is no a priori limit on number of text sections
- pr_scale is declared as unsigned long (instead of "unsigned int")
- pr_size is declared as size_t (instead of "unsigned int")
- pr_off is declared as void * (instead of "__psunsigned_t")
- the overflow bin (pr_base==0, pr_scale==2) can appear anywhere
in the profp array
- PROF_FAST has no effect */
