I had been living under apparent false impression that "realfft.c"
on which the FFT implementation in DMLIB was basically copied from
was released in public domain at some point, but it could very well
be that it never was. Correct license is (or seems to be) GNU GPL.
Thus I removing the code from DMLIB, and profusely apologize to the
author, Philip Van Baren.
It was never my intention to distribute code based on his original
work under a more liberal license than originally intended.
