[Mitgcm-support] #ifdef's versus useRUNTIMEOPTION - please read...

[mitgcm-support at dev.mitgcm.org]

I know some people are not very fond of #ifdef's.
However, keeping all options runtime options in the code
also means, keeping all options runtime for the adjoint,
and consequenlty more dependencies and more redundant
common blocks for all possible cases.

Therefore, I think we should think about adding more #ifdef's
for those cases which you won't easily change at runtime anyways.
In particular, this affects
- buoyancyrelation
- equationOfState
