Subject svn commit: r646628 - /stdcxx/trunk/src/num_put.cpp
Date Thu, 10 Apr 2008 03:26:33 GMT
Author: sebor

New Revision: 646628

URL: http://svn.apache.org/viewvc?rev=646628&view=rev
Log:
2008-04-09  Martin Sebor  <sebor@roguewave.com>

	* src/num_put.cpp [_RWSTD_OS_SUNOS]: Removed the #inclusion of
	<sunmath.h> mistakenly introduced in rev 646597 as the functions
	declared in the header are defined in libsunmath that we don't
	link with and don't want to start.
	[_RWSTD_OS_SUNOS] (__rw_signbit): Reimplemented using simple
	integer arithmetic. Needed to complete the patch for STDCXX-51	
	initially committed in rev 646396.
