This is because on Solaris, a couple of C math functions get overloaded in
C++ (and Solaris' math headers put them into the global namespace).

* #14295: Singular fails to build with GCC 4.7.x on Solaris.
On Solaris, with `__cplusplus >= 199711L`, `floor()` and `log10()` are
overloaded functions which get pulled into the global namespace,
such that calling them with an `int` gets ambiguous.
Patch `kernel/bigintmat.cc` (`patches/sage_trac_14295.patch`)
to cast parameters to `floor()` and `log10()` from `int` to
`double`, making the calls unambiguous.
