- this cannot be left as a configurable value (on windows), since it
  needs to be enabled even prior to reading the etc/controlDict file,
  in case the OpenFOAM installation path itself contains spaces.

- reduced clutter. Mostly only need to scan source tree.

- 00-dummy: use wmake/src/Allmake to get native (not cross-compiled)
  wmake toolchain binaries

- mingw uses 32-bit long regardless of -m32 or -m64 setting

- when searching for a file that may not actually exist,
  the short-cut optimization could lead to the 'constant' directory
  being ignored.

STYLE: simplify logic in points0MotionSolver::points0IO

- the scotch interface still uses non-const pointers when passing in
  values. For the ConstPrecisionAdaptor this means that we need to cheat
  with a constCast(). Using ref() will rightly trigger complaints about
  trying to modify a const object.

BUG: DimensionedField - register new field if it does not have the same name as the copy - see #1348

TODO: need to revisit

- if desired to create a tar-file without a _patch value in its name.

- add a '-SPDP' option

- remove the '-archOption' for forcing a '-m32' build on 64-bit
  architecture, which is now considered too obscure.
  Must edit files manually if this option is really required.
