Portability problems fixed by Gnulib:

@itemize

|
|
On Windows platforms (excluding Cygwin), @code{setlocale(@var{category},NULL)}
|
|
ignores the environment variables @code{LC_ALL}, @code{@var{category}}, and
|
|
@code{LANG}.
|
|
@item
|
|
On Windows platforms (excluding Cygwin), @code{setlocale(LC_ALL,@var{name})}
|
|
succeeds and sets the LC_CTYPE category to @samp{C} when it does not support
|
|
the encoding, instead of failing.
|
|
@item
|
|
On Windows platforms (excluding Cygwin), @code{setlocale} understands different
|
|
locale names, that are not based on ISO 639 language names and ISO 3166 country
|
|
names.

On Cygwin 1.5.x, which doesn't have locales,
|
|
@code{setlocale(LC_ALL,NULL)} always returns @code{"C"}.

|
On Cygwin 1.7.0, only the charset portion of a locale designation is honored.
