The patch below (against HEAD) addresses some of the concerns that were
raised earlier, notably:
1. The awful, C-ish `nl_langinfo'-based API is now replaced by a shiny
Schemey API, following Kevin's suggestion. `nl-langinfo' itself is
only used internally and not exported. As a result, most of the
`nl-langinfo'-based procedures are written in Scheme.
2. Since `nl-langinfo' is hidden from Scheme programmers, all the
`locale-' procedures are guaranteed to work, no matter whether
`nl_langinfo ()' is actually available (see the feature-conditional
macros in `i18n.scm').
As a consequence, SRFI-19 internationalization is now
straightforward as does not require feature-conditional code.
3. Previously uninterpreted `nl_langinfo ()' special return values are
now correctly interpreted. For instance, the return value for
`GROUPING' should not be interpreted as a string, as was the case
with my earlier patch.
4. No attempt is made to convert to a different encoding the strings
returned by `nl_langinfo ()'.
5. High-level procedures for locale-dependent number output are
provided, namely `number->locale-string' and
`monetary-amount->locale-string'. Both of them are implemented in
Scheme (which is relieving, really ;-)).
6. Various bugs in the C code base were fixed, a few improvements were
made (notably slight optimizations for systems without `locale_t').
7. The test suite and documentation were augmented.
I'm well aware that the patch is hard to read. Perhaps the most
important things to start with are the API in `i18n.scm' and the
corresponding documentation and test cases.
Thanks,
Ludovic.

+
+For instance, if the returned list is a circular list that contains
+only @code{3} and the thousand separator is @code{","} (as is the case
+with English locales), then the number @code{12345678} should be
+printed @code{12,345,678}.
+@end deffn
+
+The following procedures deal with the representation of monetary
+amounts. Some of them take an additional @var{intl?} argument (a
+boolean) that tells whether the international or local monetary
+conventions for the given locale are to be used.
+
+@deffn {Scheme Procedure} locale-monetary-decimal-point [locale]
+@deffnx {Scheme Procedure} locale-monetary-thousands-separator [locale]
+@deffnx {Scheme Procedure} locale-monetary-grouping [locale]
+These are the monetary counterparts of the above procedures. These
+procedures apply to monetary amounts.
+@end deffn
+
+@deffn {Scheme Procedure} locale-currency-symbol intl? [locale]
+Return the currency symbol (a string) of either @var{locale} or the
+current locale.
+
+The following example illustrates the difference between the local and
+international monetary formats:
+
+@example
+(define us (make-locale (list LC_MONETARY) "en_US"))
+(locale-currency-symbol #f us)
+@result{} "-$"
+(locale-currency-symbol #t us)
+@result{} "USD "
+@end example
+@end deffn
+
+@deffn {Scheme Procedure} locale-monetary-fractional-digits intl? [locale]
+Return the number of fractional digits to be used when printing
+monetary amounts according to either @var{locale} or the current
+locale. If the locale does not specify it, then @code{#f} is
+returned.
+@end deffn
+
+@deffn {Scheme Procedure} locale-currency-symbol-precedes-positive? intl? [locale]
+@deffnx {Scheme Procedure} locale-currency-symbol-precedes-negative? intl? [locale]
+@deffnx {Scheme Procedure} locale-positive-separated-by-space? intl? [locale]
+@deffnx {Scheme Procedure} locale-negative-separated-by-space? intl? [locale]
+These procedures return a boolean indicating whether the currency
+symbol should precede a positive/negative number, and whether a
+whitespace should be inserted between the currency symbol and a
+positive/negative amount.
+@end deffn
+
+@deffn {Scheme Procedure} locale-monetary-positive-sign [locale]
+@deffnx {Scheme Procedure} locale-monetary-negative-sign [locale]
+Return a string denoting the positive (respectively negative) sign
+that should be used when printing a monetary amount.
+@end deffn
+
+@deffn {Scheme Procedure} locale-positive-sign-position
+@deffnx {Scheme Procedure} locale-negative-sign-position
+These functions return a symbol telling where a sign of a
+positive/negative monetary amount is to appear when printing it. The
+possible values are:
+
+@table @code
+@item parenthesize
+The currency symbol and quantity should be surrounded by parentheses.
+@item sign-before
+Print the sign string before the quantity and currency symbol.
+@item sign-after
+Print the sign string after the quantity and currency symbol.
+@item sign-before-currency-symbol
+Print the sign string right before the currency symbol.
+@item sign-after-currency-symbol
+Print the sign string right after the currency symbol.
+@item unspecified
+Unspecified. We recommend you print the sign after the currency
+symbol.
+@end table
+
@end deffn
+Finally, the two following procedures may be helpful when programming
+user interfaces:
+
+@deffn {Scheme Procedure} locale-yes-regexp [locale]
+@deffnx {Scheme Procedure} locale-no-regexp [locale]
+Return a string that can be used as a regular expression to recognize
+a positive (respectively, negative) response to a yes/no question.
+
+Here is an example:
+@example
+(format #t "Does Guile rock?~%")
+(let ((answer (read-line)))
+ (cond ((string-match (locale-yes-regexp) answer)
+ "Yes it does.")
+ ((string-match (locale-no-regexp) answer)
+ "No it doesn't.")
+ (else
+ "What do you mean?")))
+@end example
+@end deffn
+
+Example uses of some of these functions are the implementation of the
+@code{number->locale-string} and @code{monetary-amount->locale-string}
+procedures (@pxref{Number Input and Output}), as well as that the
+SRFI-19 date and time convertion to/from strings (@pxref{SRFI-19}).
