	packages/language/c/libc/stdio/current: ChangeLog 
	packages/language/c/libc/stdio/current/include: stream.hxx 
	packages/language/c/libc/stdio/current/src/common: stream.cxx 
	                                                   vsnprintf.cxx 
	packages/language/c/libc/stdio/current/src/output: vfnprintf.cxx 

Log message:
	Speed-up [v]s[n]printf() functions by a factor of about 2+. In
	particular, sprintf(s, "%s", "") becomes faster 2.8 times,
	printing of every character -- 1.7 times, and, as a result, e.g.,
	printing of a string of length 50 -- 2.2 times.
	
	* include/stream.hxx (class Cyg_OutputStream): New ABC.
	(class Cyg_StdioStream): inherit from Cyg_OutputStream; make
	the destructor, write(), and get_error() virtual.
	
	* src/output/vfnprintf.cxx (vfnprintf): Use ABC Cyg_OutputStream
	instead of Cyg_StdioStream.
	
	* src/common/vsnprintf.cxx (class Cyg_VsnprintfStream): New class
	that specializes Cyg_OutputStream for output to a string.
	(vsnprintf): Use Cyg_VsnprintfStream for printing to a string.
