Subject: Clang doesn't like -Wno-unused-but-set-variable
X-Git-Url: http://81.2.79.47:8989/gitweb/?a=commitdiff_plain;h=805564dcf2cf2f55fb4860f8224ae82edee75395;p=zefram%2Fminetest%2Fminetest_engine.git

Clang doesn't like -Wno-unused-but-set-variable

The release versions of CMake don't yet properly support flag checking
in Clang, so we need to exclude it explicitly for the time being.
