warning: address of array 'config.conffile' will always evaluate to 'true' [-Wpointer-bool-conversion]

Building yaz 5.32.0 with recent clang compiler emits these warnings:

yaz-icu.c:569:16: warning: address of array 'config.conffile' will always evaluate to 'true' [-Wpointer-bool-conversion]
    if (config.conffile && strlen(config.conffile))
        ~~~~~~~^~~~~~~~ ~~
yaz-icu.c:572:16: warning: address of array 'config.print' will always evaluate to 'true' [-Wpointer-bool-conversion]
    if (config.print && strlen(config.print))
        ~~~~~~~^~~~~ ~~
2 warnings generated.

Although 5.32.0 is an older version I think the code has not yet been changed to fix this:

yaz/util/yaz-icu.c

Lines 567 to 571 in dc6defa

	if (config.conffile && strlen(config.conffile))
	process_text_file(&config);
	if (config.print && strlen(config.print))
	print_info(&config);
