Subject: nv50/ra: `isinf()` is in namespace `std` since C++11.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f525db6358fbaa7b4296d2e6484e0b1ae703ac78;p=mesa.git

nv50/ra: `isinf()` is in namespace `std` since C++11.

This fixes a compile error while building Nouveau with C++11 enabled (and
glibc >= 2.23). This happens if SWR is enabled, as it forces C++11.
