tab uses non-standard constants

[Former user]

Using the makefile the build fails on M_PI and M_E definitions. I am using version 13.4 of the http://nuwen.net distribution of g++ for Windows.

There is some discussion in the following link regarding this: http://stackoverflow.com/questions/1727881/how-to-use-the-pi-constant-in-c
