I absolutely scoffed when I read this, knowing that we went around on this more than 10 years ago.  But I did a search to make sure, and there is no question the %%GlobalVariables Design, which gets mixed into the "world" above the root, contains the bad definition.  Our internal definition (in c++) looks like this:

#ifndef M_PI
// 50 places: 3.1415926535897932384626433832795028841971693993751
#define M_PI    ((double)3.1415926535897932384626433832795028841971693993751L)
//#define M_PI    3.14159265358979323846 (prior to July 9, 2001)
#endif

The good news is you can fix this on your installations by modifying the xxGlobalVariables.iks file.

Thanks for the heads up.  It is hard to believe how long this must be been there.
