Description Martin Wolters 2017-10-01 07:58:26 UTC

Trying to install llvm-3.9.1-r1 with abi_x86_32 fails due to what seems to me to be a typo (-std=c*+11 instead of -std=c++11).

Relevant portion of the build log:

Attaching emerge --info. The full build log is several MB in size, so I can't attach it.
I uploaded it here: http://korova.vellocet.org/b/build.log
