Version 2.1.5 (3/24/2003)
* Bug fix: Fortran wrappers were disabled in version 2.1.4.
Version 2.1.4 (3/16/2003)
* Upgraded to newer versions of autoconf, etcetera, to fix compilation
problems on various recent systems.
* The configure script no longer picks the wrong architecture flags
(which caused FFTW to crash) on newer IBM POWER machines running AIX.
* Multi-threaded transforms should now utilize multiple CPUs on
Solaris (which creates threads in single-processor mode by default).
* Added experimental support for OpenMP (and SGI MP) compiler
parallelization directives in the multi-threaded transforms,
instead of using explicit thread spawning. Enable by configuring
--with-openmp or --with-sgi-mp in addition to --enable-threads.
* Expanded FAQ.
