Comment(by stefan):

 The reason for the #undef's is that each COIN-OR project has it's own
 config_xxx.h file, but a higher level project may need to read the
 configuration of the lower level project by including it's config_xxx.h
 file. Thus, there are wrappers XXXConfig.h which include the actual
 config_xxx.h and undefine macros that are common among different
 config_xxx.h files (and they define some macros to default values in case
 one builds without autotools).

 Unfortunately, it does not always seem possible to avoid that a public
 header of a project includes its config_xxx.h file (well, at least in my
 case it may be lazyness ;-)). The easy workaround is to include the
 XXXConfig.h file before your config_xxx.h file, if possible.

 I do not see a possible fix for all projects. If you think that a
 particular project (e.g., Osi), could make it's inclusions of XXXConfig.h
 private, then I suggest to submit a ticket there, preferably with a patch
 file included :-).

 Anyway, thanks for pointing this out. I leave the ticket open since it is
 surely something to work on.

 Stefan
