There's a number of warnings from clang in readconf.c The dangling else at 3802 and this and the "|| &&" construct at 4311 don't need much further comment:
readconf.c:3802:7: warning: add explicit braces to avoid dangling else
[-Wdangling-else]
else
^
readconf.c:4311:44: warning: '&&' within '||' [-Wlogical-op-parentheses]
|| Ustrncmp(current, "hide", 4) == 0 && isspace(current[4])
At line 4302 there's an issue with char / unsigned char ... since strlen
wants "const char *" but current is "const uschar *" I think the
correct change is from
else if (current[strlen(current)-1] == ':' && !Ustrchr(current, '='))
to
else if (current[Ustrlen(current)-1] == ':' && !Ustrchr(current, '='))
since Ustrlen exists for precisely this purpose!
Finally at line 4315 clang complains
readconf.c:4315:11: warning: using the result of an assignment as a
condition without parentheses [-Wparentheses]
if (p = Ustrchr(current, '='))
that's because clang is concerned that the programmer might have
intended to write p ==
so the simplest fix is (inelegantly)
if ((p = Ustrchr(current, '=')))
but I'd write it as two lines myself for clarity:
p = Ustrchr(current, '=');
if (p)
