There are at least a couple of reasons. Primarily it's because it's a
GAWK extension. The tests in the Makefile that run my script against
different AWK variants were not added for debugging this problem. I want
this script to be fairly portable although in practice, I only care
about MAWK right now. Secondarily, I run a statically linked copy of
GAWK built against musl libc, so I don't think it would be an option
even if I only cared about supporting GAWK.
