Solaris 10 /usr/bin/awk (which is the closest to the original Awk implementation
that I know of) definitely does not work with tzdb 2018e, as Solaris 10 awk
lacks support for many POSIX features, starting with the -v option.
tzdb uses only awk features standardized by POSIX since 1992. At this point, a
POSIX-1992-or-later awk should be available on every development platform of
interest to tzdb, and it shouldn't be much trouble to ask developers to update
to a 25-year-old standard or better. On Solaris 10, for example, you can use
/usr/bin/nawk or /opt/sfw/bin/gawk (both shipped as part of Solaris 10). On
Debian/Ubuntu/etc. you can use gawk.
