improving compile times

[yakra]

for o in $(find . -name \*.o); do
  rm $o;
  printf "%s\t$o\n" $(2>&1 time -f %e make $o > /dev/null);
done

• [ ] won't do much but #291

fmt (mostly)

• [ ] #286
• [ ] Comment out HGEdge::intermediate_point_string()
• [ ] maybe use snprintf for low-impact functions?
  • [ ] GraphListEntry::tag()
  • [ ] ElapsedTime::et()
• [ ] HighwayGraph.cpp
  • [ ] Separate out ST/MT, fmt bits
  • [ ] Create HGVertex::tmg_line?
• [ ] Route::write_nmp_merged(): combine adjacent calls into one?
• [ ] read_wpt.cpp move fmt functionality out:
  • [ ] Datacheck::add_long_segment
  • [ ] Datacheck::add_sharp_angle
• [ ] Waypoint::nmplogs: combine adjacent calls into one?
• [ ] WaypointQuadtree.cpp
  • [ ] Separate out ST/MT, fmt bits
  • [ ] Datacheck::add_duplicate_coords
  • [ ] confirm WaypointQuadtree::str() usused; comment out
• [ ] allbyregionactive*
  • [ ] lose the ifdef
  • [ ] combine into one function via pointer-to-member?
• [ ] sql_file:
  • [ ] an "sqleton" to handle the ST/MT printouts, calling functions for each table
  • [ ] compile table functions separately to minimize dependencies? OTOH, this may be outweighed by the overhead of fmt. fmt & non-fmt translation units?
• [ ] rdstats: lol combine adjacent calls?

ST/MT

TBD. Haven't looked into this much yet.
