[Coin-discuss] name clashes in preprocessor directives

Hi,

This would only help if you include your own config.h header after any of 
the COIN headers.  Probably this is not the way you want to use it, since 
one typically includes one's own config.h very early since it contains all 
the configuration information.  In that case, you will have to undefine 
the macros that are defined in YOUR config.h, since they will otherwise 
clash with the COIN ones.

Cheers,

Andreas
