has also given us a speed up to the build process (--quick-build
configure option).

configuration fixes and updates; Stephen Turnbull for build fixes,

Lots of updates from Ben Wing (as always), also from Andy Piper, Mike
Sperber, and Stephen Turnbull with lots of documentation updates and

   -- Type names should be relatively short, with the first letter
      capitalized and no underscores if they can be avoided.
   -- "*count" == zero-based quantity.  Includes sizes, offsets, and indexes.
   -- "*bpos" == one-based buffer position.
   -- "Char" refers to internal-format characters, not to the C type "char".
