Give compiler the extra braces it recommends. DBio.c edited as my original change was caught out by the incorrect indention of the 'else' keyword and my modification would have caused a NULL deref. Exactly the kind of issue this warning is trying to prevent. CmdTZ.c:417:20: warning: suggest explicit braces to avoid ambiguous 'else' DBio.c:1422:12: warning: suggest explicit braces to avoid ambiguous 'else' DBpaint2.c:285:12: warning: suggest explicit braces to avoid ambiguous 'else' DBpaint2.c:384:12: warning: suggest explicit braces to avoid ambiguous 'else' GCC14 -Wall cleanup series [-Wdangling-else]
