The master branch of rtlsdr (HEAD at 4520f00) currently does not compile on macOS and fails with following compiler error:

See the attached log file homebrew-librtlsdr-macos-error.log for the full compiler output.

The issue seems to have been caused by a fairly recent commit (a03198c). The alleged commit introduced a generic time struct and as far as I can judge the author forgot to update the time structure for Apple platforms, i.e. macOS.

I tried to fix the issue with the attached patch homebrew-librtlsdr-macos.patch but I'm not familiar with the rtlsdr code base and no C expert, so please verify it as I only tested whether it compiles (which "works for me"™). Please let me know if you want me to test the code.
