Hi,
this patch adds generation of params.list, a file containing a list of
names of all the parameters in params.def.
By including params.list in params.h, rather than params.def itself, we
prevent recompiling the 118 c files that include params.h for trivial
changes in params.def, such as f.i. changing the default value of a
parameter.
I did a minimal build with the patch, and tested the behaviour by doing
both trivial an non-trivial changes in params.def, and rebuilding.
Any comments?
Thanks,
- Tom
