slib3a4 news:
+ Discreet Fourier Transforms of any rank.
+ Added SRFI-94 and SRFI-23
From Ivan Shmakov
* scheme48.init (file-exists?): Much simplified.
From Kevin Ryde
* guile.init: Fixed line-i/o in Guile >= 1.8.
* srfi-1.scm (reduce-right): Was infinite loop.
From Ben Goetter
* pscheme.init: Revised for Pscheme 1.3.
From Aubrey Jaffer
* dft.scm (dft, dft-1): Added routines which use the best method
for decimating each dimension.
(dft:dft): Call 1d transform only with contiguous arrays.
(sft, sft-1, fft, fft-1): Added optional array-prototype argument.
(sft, sft-1): Slow Fourier transforms added.
(dft:sft1d!, dft:fft1d!): Flipped polarity of exponent to agree
with http://en.wikipedia.org/wiki/Discrete_Fourier_transform.
Generalized to any positive rank.
Renamed from "fft.scm".
* slib.texi (Sorting): Updated; cleaned up.
(Sorting): Added optional KEY arguments.
* sort.scm (merge!): Fixed.
(sort!): Swap pairs so that list returned EQ? to argument.
(sort, sort!, sorted?, merge, merge!): Added optional KEY argument.
* tzfile.scm (tzfile:read): Use subbytes instead of subarray.
* byte.scm (subbytes): Added.
(subbytes-read!, subbytes-write): Renamed from substring-...
* slib.texi (Irrational Real Functions)
(Irrational Integer Functions): Sections added.
* math-integer.scm, math-real.scm: Added SRFI-94.
* slib.texi (Feature): Indexed number-system attribute features.
* require.scm: Tightened number-system attribute features.
* modular.scm (modular:characteristic, modular:+): Recoded so `-'
has no more than 2 arguments.
(mod, rem): Removed.
(modular:characteristic): Renamed from modulus->integer.
(modular:expt): Handle base = modulus - 1. Corrected documentation.
* srfi-23.scm (error): Added.
* simetrix.scm (SI:unit-infos): Updated u and eV to CODATA-2002.
* peanosfc.scm (peano-coordinates->integer)
(integer->peano-coordinates): Fixed; were broken for rank != 2.
* subarray.scm (subarray): Handle reverse index ranges.
* pnm.scm (pnm:array-write): Don't lose comments when recursing.
* slib.spec (%files): Added man1/slib.1.gz.
* grapheps.ps (sign): Cleaner than inline code.
(setup-plot): Now handles decreasing axes.
* grapheps.scm (plot): Handle list of lists data.
* root.scm (integer-sqrt): Streamlined.
(secant:find-root-1): Fixed internal argument mismatch
for number-of-iterations case.
* getopt.scm (*argv*): Removed (define *argv* *argv*).
* solid.scm (solid:prism, solid:lumber): Added.
* array.scm (make-shared-array): Work for rank-0 arrays.
(equal?): Compare element-by-element of two arrays.
(make-array): Return string or vector even if prototype is a
strict array.
(make-array): Return simple string or vector if possible.
* strcase.scm (symbol-append): Work with case-sensitive or
case-insensitive symbols.
* Makefile (dvi, pdf): New tetex-3.0(-20.FC5) broke them -- fixed.
(docs): Added target to make all documentation files and invoke xdvi.
(texifiles): Added fdl.texi.
(S48LIB): Renamed from LIB.
(S48SLIB): Subdirectory of implementation-vicinity.
(install48): Make $(S48SLIB) directory and files.
* indexes.texi (Index): Removed "Full Table of Contents".
* slib.texi (SRFI): Added @ftindex entries for SRFIs.
Converted to @copying and GNU Free Documentation License.
* mklibcat.scm: Change all slib files to `source'.
* require.scm (catalog:get): Handle (home-vicinity) being false.
(catalog:get): mklibcat is `source'.
(require): Don't provide `new-catalog'.
* *.init, Template.scm, require.scm (slib:features): Renamed from
*features* to avoid conflict with Guile identifier.
* vscm.init, umbscheme.init, Template.scm, t3.init, STk.init,
scsh.init, scheme2c.init, RScheme.init, mitscheme.init,
macscheme.init, jscheme.init, gambit.init, elk.init,
DrScheme.init, chez.init, bigloo.init (slib:error): Capture
`error' identifier (to survive redefinition).
* elk.init (slib:error): Removed bad insertion.
* bigloo.init (slib:features): Lacks object-hash.

* guile.init (char-code-limit): Reduced to workaround string
ordering bug.

from define to set! to eliminate guile-1.8.0 warning:
WARNING: (guile-user): imported module (ice-9 slib) overrides core binding
(defined?, in-vicinity, port?, 1+, -1+, 1-): Removed
definitions duplicating Guile defines.
(*features*): Set, rather than define.
(browse-url): Added.
* scheme48.init: (slib:load-compiled): Loads a native SRFI module.
