If anybody is interested in the FFTW wrapper routines, feel free
to contact me by email. At present they handle only a subset of the
FFTW routines (1d and 2d) and documentation is rudimentary at best.
I have some example IDL progs though. Makefiles can be provided for
SUN-Solaris (cc and gcc) and for M$ Visual C++ 5.0.

BTW: I very much doubt if it's against the GPL to distribute code, which
refers to subroutine libraries under GPL as long as I do not include
these routines or a compiled binary.
