Hi Chris,
I tried running the same build command with the "g++ -E" option. The error line gets turned into:
ESU = 2, EAST_SOUTH_UP = 2, 2 = 2, EAST_SOUTH = 2, FLIP_Y = 2,
Obviously ES is being defined to 2 from somewhere else.
The error does not get fixed if we #undef ES before the #include of "polygon.hpp" in the "main.cc" file, but it does if we insert an #undef directly before the declaration of the enum in "polygon.hpp" itself. (with no other errors reported)
On further inspection (and checking the GCC debug output options) it looks like that it is being defined in "/usr/include/sys/regset.h"
