Comment (by andre.holzner@…):

 interesting that #42763 was submitted at more or less the same time as
 activity on this ticket.
 I tried the patch there and it also builds for me on OSX 10.9. The patch
 there deactivates
 a bit less of the file include/Inventor/C/base/math-undefs.h than what I
 attached here
 (it leaves the compile time error intact when this file is included from
 code outside Coin),
 so maybe the patch in #42763 is preferable.
