 Christian Reisswig (and I and Christian Ott and Philipp Moesta, but we did
 not properly identify it as a bug) found that adding or removing a
 parameter does not trigger a recompile of source files where the parameter
 was used. To reproduce, take a compiled configuration and eg. comment out
 a parameter in (any) thorn's param.ccl. Recompile and notice that no
 source files are recompiled (but
 configs/<CONFIG>/bindings/Parameters/<Thorn>_Parameters.c is). This
 manifests itself in wrong parameter values in the thorns (but correct
 values as returned by CCTK_ParameterGet).

 I checked and the file containing the updated parameter structure
 (configs/<CONFIGNAME>/bindings/include/ParameterCPrivate<THORNNAME>.h)
 '''does''' appear in the source file's auto-dependency file
 (configs/<CONFIGNAME>/build/<THORNNAME>/<SOURCEFILE>.c.d) but that files
 seems to be completely ignored (ie. touch'ing a file listed in there does
 not trigger a recompile).

 I am making this a critical bug since it affects every single thorn.

 I attach a trivial thorn to display the issue but any configuration you
 have sitting around will do.
