I tried to build the 2018c release of tz code and data and found that file zishrink.awk line 40: gsub(/[\f\r\t\v ]+/, " ", line) erroneously changed all 'v' characters to spaces as '\v' was not recognized as an escape sequence (hence handled as 'v') on my OS. Changing the line to gsub(/[\f\r\t\013 ]+/, " ", line) or removing '\v' from the regexp allowed the build to be possible again.

Thanks for the bug report. I installed the attached, which should appear in the next release. POSIX requires awk to support \v but if mawk can stray from POSIX I suppose macOS awk can too.
