Compile problem: Where is public_ids_strings defined

Got a compile problem and can't find where public_ids_strings is defined ?
I did grep -r too?

#define NUMBER_OF_WML_EXTERNALID ((long)
sizeof(public_ids_strings)/sizeof(public_ids_strings[0]))
gw/wml_compiler.c:            if (octstr_compare(externalID,
octstr_imm(public_ids_strings[i].string)) == 0) {
gw/wml_compiler.c:                (*wbxml)->wml_public_id =
public_ids_strings[i].value;
wmlscript/gw/wml_compiler.c:#define NUMBER_OF_WML_EXTERNALID ((long)
sizeof(public_ids_strings)/sizeof(public_ids_strings[0]))
wmlscript/gw/wml_compiler.c:            if (octstr_compare(externalID,
octstr_imm(public_ids_strings[i].string)) == 0) {
wmlscript/gw/wml_compiler.c:                (*wbxml)->wml_public_id =
public_ids_strings[i].value;


But where is it defined? Missing file??

Thanks
