Do you have full code base and all package build about this warning?
I can some for loop like below in UefiLib.c AddUnicodeString2(). And
there maybe many other places have similar cases I guess since I never
met this build failure before.
for (; *SupportedLanguages != 0 && *SupportedLanguages == ';';
SupportedLanguages++);
What's the real value of this build warning? And could you disable this
warning the tool chain?
Thanks,

This code change removes the warning.
