Use G_N_ELEMENTS rather than a custom macro.

Sun Jul  1 20:16:25 2001  Owen Taylor  <otaylor@redhat.com>

	* glib/guniprop.c (g_unichar_totitle): Use G_N_ELEMENTS
	rather than a custom macro.

	* glib/gen-unicode-tables.pl: Adapt to changes in table
	formats for Unicode 3.1

	* glib/gunicode.h glib/guniprop.c glib/gunichartables.h
	  glib/gen-unicode-tables.pl: Add case conversion functions
        g_utf8_casefold, g_utf8_strup, g_utf8_strdown.

	* tests/unicode-caseconv.c tests/gen-casefold-txt.pl
	  tests/gen-casemap-txt.pl tests/casefold.txt
	  tests/casemap.txt: Test cases for case conversion.

	* glib/gunicode.h glib/gunidecomp.[ch] glib/gunicomp.h
	  glib/gen-unicode-tables.pl: Add function to do Unicode
        normalization g_utf8_normalize().

	* tests/unicode-normalize.c: Test program for case conversion.

	* glib/gunicode.h glib/gunicollate.c: Add collation functions
	g_utf8_collate, g_utf8_collate_key.

	* test/unicode-collate.c: Test program for collation.

	* glib/gdate.c (g_date_fill_parse_tokens): Fix uninitialized
	variable.

	* glib/gdate.c (g_date_strftime) docs/Changes-2.0.txt:
	Make work with UTF-8 even if the locale isn't UTF-8 based.
	Still somewhat of broken, if the format string contains
	characters not representable in the current locale, will warn
	and not work.

	* glib/gdate.c: Use UTF-8 normalization and casefolding.
