In fact the change is fairly easy, just replace

   dval = gensub (/^.*\{(.*)\}.*$/, "\"\\1\"", "g", dval);

with

   gsub (^.*\{(.*)\}.*$/, "\"\\1\"", dval);

at line 413 and

  class_name = gensub (/^.*BEGIN_PROPERTIES\((.*)\)/, "\\1", "g");

with

  class_name = $0;
  gsub (/^.*BEGIN_PROPERTIES\((.*)\)/, "\\1", class_name);

at line 439. I believe gsub is compatible with awk.
