svn commit: r631231 - in /stdcxx/branches/4.2.x/etc/config/src: FLOAT.cpp
LDBL_PRINTF_PREFIX.cpp float_defs.h
Author: faridz
Date: Tue Feb 26 06:40:16 2008
New Revision: 631231
URL: http://svn.apache.org/viewvc?rev=631231&view=rev
Log:
2008-02-26 Farid Zaripov <fa...@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.
