Resolved Fixed:
- fixed compiler detection of MinGW as supplied by installer is not working
 
Regressions/Confirmed/Annoying/Common bugs:
Yes, it can detect compiler  in my  MinGW64  directory now , but the compiler is judged as "GNU GCC Compiler" ,  not exactly as "GNU GCC MinGW64 Compiler" . Although this may not be relevant, the compiler still works normally,  but I can't stand it, just because I'm am a perfectionist ,virgo.
P.S.  Now that  every  nightly builds  C::B needs the other two files of the corresponding version  to run,  and  most easiest way is to unzip both of them into the same directory where you unzipped the nightly  , why not pack them together into a file,
Let's download once and unzip once  instead of  download three times and unzip three times 

.
