[erlang-questions] Two little questions

[Olivier BOUDEVILLE]

Hi,

sorry if it's an obvious question, but how to specify to the erl 
interpreter which include directories should be scanned for *.hrl file 
when using 'c(my_module).' ? (a I tried with no luck '-code_path_cache' 
and '-pa'/'-pz' (I suppose both must be for precompiled modules (beam)), 
but I did not find header counterparts (I lack the C/C++ -I directive). 
Had to create a symlink instead. 

Another question : -ifdef/-endif clauses cannot be used inside functions 
apparently, instead they may be used around helper functions, but if a 
non-exported function just end up being defined as :

"""
f() ->
        ok.
""" 

will calls to it (thus from the same module) be optimized away if they 
ignore its result ?

Thanks in advance for any hint,
best regards, 

Olivier.
