I don't very much like that code -
Me neither, just wanted to address the issue.
but OTOH I'm thinking to use double precision to compute the table
this time around, so whatever imprecision there is should be minimal :)
Also, instead of accumulating the phase you should calculate it for
every point:
#ifndef M_PI
#define M_PI 3.14159265358979323846264338327950288
#endif
...
for (int i = 0; i < COSTABSIZE + 1; i++)
fp[i] = cos(2.0 * M_PI * i / (double)COSTABSIZE);
This should ensure that the table is symmetric, unless the underlying
cos() function is broken :)

Sounds good to me!
Just to be sure, you will also try to make the new table symmetric,
right? See
