- compile into linux64Gcc44, linuxGcc44 to avoid clashes during testing
- continue to use gmp-4.2.4 since gmp-4.3.x might be miscompiled with
  a system gcc-4.3.2

- search for 'lnInclude' rather than 'Make' by default
  This gives better general behaviour for rebuilding.

- update foamPack* scripts accordingly

- skip including java rather than having recursive includes
  (and too many files open error) when WM_JAVAC_OPTION isn't defined.

- change name of environment variable from $WM_OS -> $WM_OSTYPE
  as a better description

- place wmkdep and dirToString executables under
  utilbin/$(WM_ARCH)$(WM_COMPILER).
  This helps somewhat when copying rules about, and might help when creating
  general rules.

- added rules for gcc-4.3 in preparation for switching to gcc-4.4

- added 'clean' target for wmake/src/Makefile
  It is probably reasonable to separate the binaries from the rules (TODO)

- this seems to be the most sensible solution.
  The changed time stamps on the links doesn't seem to bother make at all.

Changing template-depth back to 40.  Adding initialisation functions and constantProperties construction.

Adding relaxation calculation that adjusts to changes in runTime controls during a run.  Experimenting with primary alignment rotations to achieve boundary alignment.  Altering template depth back to 60 after master merge conflict resolution.

- avoids problems with finding files based on FOAMversion
  (reported by Mattijs)

Changed "flex++" to "flex --c++" to avoid the need to create the link from "flex" to "flex++" after installing "flex".
