Subject svn commit: r631231 - in /stdcxx/branches/4.2.x/etc/config/src: FLOAT.cpp LDBL_PRINTF_PREFIX.cpp float_defs.h
Date Tue, 26 Feb 2008 14:40:17 GMT
Author: faridz

New Revision: 631231

URL: http://svn.apache.org/viewvc?rev=631231&view=rev
Log:
2008-02-26  Farid Zaripov  <farid_zaripov@epam.com>

	Merged r629825 from trunk.
	* etc/config/src/float_defs.h: New file with a definitions
	of the floating point constants.
	* etc/config/src/FLOAT.cpp: #including the "float_defs.h"
	instead of defining the floating point constants in file.
	* etc/config/src/LDBL_PRINTF_PREFIX.cpp: Ditto.

	Merged r629900 from trunk.
	* etc/config/src/FLOAT.cpp: Updated comment, erroneously changed in r629825.
