cppunit: gcc 4.2 vs 4.6 and libreoffice too

[Andriy Gapon]

Not related to the thread-starting message, but another issue I've found with
cppunit.  When it is compiled with GCC 4.6 it fails to use abi::__cxa_demangle in
TypeInfoHelper::getClassName because CPPUNIT_HAVE_GCC_ABI_DEMANGLE is not defined.
That happens because configure script fails to detect abi::__cxa_demangle
usability.  And that is caused by a missing prototype/header for free(3) function
used in the detection code.

I suggest the following patches.
For configure:
