Subject: util/u_math: Fix C++ include of u_math.h on MSVC.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dbc1f3677c1deb32358a6a53f0ad3638a78c7c4f;p=mesa.git

util/u_math: Fix C++ include of u_math.h on MSVC.

GNU C++ compiler declares the C99 lrint, etc. when _GNU_SOURCE is
defined, but MSVC does not.

Trivial.
