Although gawk (GNU awk) is available for the vast majority of Unices,
it is not included out of the box in most cases (exceptions are most
Linux distros and some BSDs). But it is fair to expect that a *nix or
*nix-like OS has *an* awk implementation by default, which should be
POSIX compliant. Which portions of gawk are POSIX and which ones are
GNU extensions should be described in the man page or texinfo doc for
gawk. Or, if unsure, one may look into the Single Unix Specification
V2 (the POSIX specs are not available w/o paying for it). It describes
what features a POSIX/SUS2 compliant awk must have:

If you have gawk you may perform a quick test of your awk script using
the gawk options --traditional or --posix.
