Description Patrick ALLAERT 2012-08-06 15:40:54 UTC 
Compile ends because of M_PI not being defined in docs/tools/shadow.c:

shadow.c(16): error: identifier "M_PI" is undefined
      return ((1 / (2 * M_PI * r)) *

This is weird since the file correctly contains:
#include <math.h>
Comment 1 Patrick ALLAERT 2012-08-06 15:43:27 UTC 
Replacing M_PI with: 3.14159265358979323846
solves the problem and gtk+ can be fully compiled with only this change.

Is this still valid with  latest gtk+-3.4.x?
