This package uses sse3 simd flags. However, sse3 is in x86_64-v2 instead of x86_64. Some users with x86_64 instead of x86_64-v2 will not be able to use this package.

Additional info:
* package version(s)
* config and/or log files etc.
* link to upstream bug report, if any

The wording is a little off. The ISA levels defined by x86_64-v{2,3,4} are only a recent invention. Most CPU's from the last 15-20 years have SSE3 instructions so real world impact is limited. The real issue is that current baseline Arch advertises/compiles with -march=x86-64 and therefore shouldn't unconditionally distribute binaries compiled with `-msse3' (unless of course there is runtime logic to DTRT, which in this instance there isn't AFAICT).
