Update.
1999-06-21  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* libio/Makefile (routines): Add putwchar and putwchar_u.

	* libio/putwchar.c: Include <wchar.h> instead of "stdio.h".
	* libio/putwchar_u.c: Likewise.  Use _IO_stdout instead of
	stdout.  Fix parameter name.

	* libio/getchar.c: Consistently use _IO_stdin instead of stdin.
	* libio/getchar_u.c: Likewise.

	* libio/putchar_u.c: Use _IO_stdout instead of stdout.

1999-06-21  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* include/features.h (__GNUC_PREREQ): Don't generate `defined' via
	macro expansion---it's undefined.  Properly parenthesize
	substituted parameters.
	(__GLIBC_PREREQ): Likewise.
