svn commit: r1484783 - /openoffice/trunk/main/sal/inc/sal/mathconf.h
Author: hdu
Date: Tue May 21 12:45:44 2013
New Revision: 1484783
URL: http://svn.apache.org/r1484783
Log:
prefer standard isfinite()
which should be available in math.h according to C99, C++99, SUSv3, etc.
unless GCC bug 14608 hits us where cmath undefines isfinite as macro
