Error during make - isarray is a built-in function

[DanRStevens]

/bin/bash ./libxlibtrace-functions.h.sh
awk: cmd. line:29: function isarray(t) {
awk: cmd. line:29: ^ `isarray' is a built-in function, it cannot be redefined

Edit: Tested on Ubuntu 20.04
Renaming the function allows build to proceed, though it fails later on.

Thanks. I haven't used this in years. Feel free to send a PR to rename the function, and another issue for the later failure.
