X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fb8d46385113884eb18abef5bee948c955f298ae;p=gcc.git

std_streambuf.h (__copy_streambufs): Remove the first, unused, basic_ios<> parameter.

2003-11-27  Paolo Carlini  <pcarlini@suse.de>

	* include/std/std_streambuf.h (__copy_streambufs): Remove
	the first, unused, basic_ios<> parameter.
	* src/streambuf-inst.cc: Likewise.
	* include/bits/streambuf.tcc: Likewise.
	* include/bits/istream.tcc (operator>>(__streambuf_type*)):
	Tweak accordingly the call.
	* include/bits/ostream.tcc (operator<<(__streambuf_type*)):
	Likewise.

	* include/bits/streambuf.tcc (__copy_streambufs): Remove
	redundant try/catch.
