Warning, CppUnit supports Microsoft Visual C++, but the function=20
isfinite() is not available on this compiler. However, a similar=20
function called _finite() is provided. I have checked this on Visual C++=20
6, Visual Studio 2003 and Visual Studio 2005.

It may be a good idea to put the following macro in the file=20
cppunit/config/config-msvc6.h :
#define isfinite(x) _finite(x)

Additionnally, it may be good to create a CPPUNIT_HAVE_ISFINITE macro=20
and use it where it is needed.
