- *	Convert Windows locale name to the ISO formatted one
- *	if possible.
+ * Convert a Windows setlocale() argument to a Unix-style one.
  *
- *	This function returns NULL if conversion is impossible,
- *	otherwise returns the pointer to a static area which
- *	contains the iso formatted locale name.
+ * Regardless of platform, we install message catalogs under a Unix-style
+ * LL[_CC][.ENCODING][@VARIANT] naming convention.  Only LC_MESSAGES settings
+ * following that style will elicit localized interface strings.
+ *
+ * Before Visual Studio 2012 (msvcr110.dll), Windows setlocale() accepted "C"
+ * (but not "c") and strings of the form <Language>[_<Country>][.<CodePage>],
+ * case-insensitive.  setlocale() returns the fully-qualified form; for
+ * example, setlocale("thaI") returns "Thai_Thailand.874".  Internally,
+ * setlocale() and _create_locale() select a "locale identifier"[1] and store
+ * it in an undocumented _locale_t field.  From that LCID, we can retrieve the
+ * ISO 639 language and the ISO 3166 country.  Character encoding does not
+ * matter, because the server and client encodings govern that.
+ *
+ * Windows Vista introduced the "locale name" concept[2], closely following
+ * RFC 4646.  Locale identifiers are now deprecated.  Starting with Visual
+ * Studio 2012, setlocale() accepts locale names in addition to the strings it
+ * accepted historically.  It does not standardize them; setlocale("Th-tH")
+ * returns "Th-tH".  setlocale(category, "") still returns a traditional
+ * string.  Furthermore, msvcr110.dll changed the undocumented _locale_t
+ * content to carry locale names instead of locale identifiers.
+ *
+ * MinGW headers declare _create_locale(), but msvcrt.dll lacks that symbol.
+ * IsoLocaleName() always fails in a MinGW-built postgres.exe, so only
+ * Unix-style values of the lc_messages GUC can elicit localized messages.  In
+ * particular, every lc_messages setting that initdb can select automatically
+ * will yield only C-locale messages.  XXX This could be fixed by running the
+ * fully-qualified locale name through a lookup table.
+ *
+ * This function returns a pointer to a static buffer bearing the converted
+ * name or NULL if conversion fails.
