[Coin-discuss] name clashes in preprocessor directives

We face a similar problem since all COIN projects use autoconf
independently, i.e., those preprocessor macros are defined for all
projects (such as CoinUtils, Clp, etc). The way we go around this
error/warning message is by undefining those macros, with
/* undefine macros that could conflict with those in other config.h
We do this by never directly including config_coinutils.h in our source
codes, but instead we include a wrapper, which includes the autoheader
file config_coinutils.h but immediately undefines the macros that lead to
You may have a look at the CoinUtils/src/CoinUtilsConfig.h as an example,
in case you decide to handle this in your code in a similar manner.
I hope this helps,
