0dcd7e6153 Modify read and print of combining characters
Since combining characters, such as accents, modify the appearance of the
previous letter, it looks awkward in its character literal form (#\name)
since it modified the backslash.  This instead prints the combining
character on a small circle.

Ah, we already had scm_i_pthread_mutex_trylock lying around; that made
things easy.
A second timing test with A(3,9) and this version of the patch (based
on 1.9.1) shows the same improvement.

889975e51a Add full Unicode capability to ports and the default reader
Ports are given two additional properties: a character encoding and
a conversion failure strategy.  These properties have getters and setters.
The new properties are used to convert any locale text to/from the
internal representation of strings.

If unspecified, ports use a default value. The default value of these
properties is held in a fluid.  The default character encoding can be
modified by calling setlocale.

ISO-8859-1 is treated specially.  Since it is a native encoding of
strings, it can be processed more quickly.  Source code is assumed to be
ISO-8859-1 unless otherwise specified.  The encoding of a source code
file can be given as 'coding: XXXXX' in a magic comment at the top of a
file.

The C functions that deal with encoding often use a null pointer
as shorthand for the native Latin-1 encoding, for efficiency's sake.

  encodings based on the locale's character encoding

  functions scm_getc, scm_unget_byte, scm_ungetc,

a4dbe1ac3d Avoid clash with system setjmp/longjmp on IA64
Problem was that if an application includes both libguile.h and the
