Subject svn commit: r650367 - /stdcxx/trunk/include/valarray.cc
Date Tue, 22 Apr 2008 03:24:45 GMT
Author: sebor
Date: Mon Apr 21 20:24:44 2008
New Revision: 650367

URL: http://svn.apache.org/viewvc?rev=650367&view=rev
Log:
2008-04-21  Martin Sebor  <sebor@roguewave.com>

	* include/valarray.cc (shift, cshift): Removed assumptions about
	value_type being constructible from int. Revealed by regression
	test for STDCXX-316 committed in rev 650366.
	(cshift): Replaced a functional cast involving _RWSTD_PTRDIFF_T
	with a C-style one in case the macro expands to something like
	"signed long."
