Hi Peter,

I suppose that the issues are not suppressed by make but caused by
overly picky default compiler flag setting of your Xcode project.

Implicit conversion is a feature of C since its early days, so warning
about its usage is quite an annoyance for almost every C/C++ programmer.
Consider the following:

      X←4 3⍴0
      Y←3 3⍴X
      Y←3 3⍴X

Assignment looses elements.

I believe a lot of people would rightfully complain about it

Best Regards,

If I make a standard  Xcode C++ project and simply add only files main.hh and main.cc
then compile I get 24 Value Conversion Issues all of the type 
Implicit conversion loses integer precision: 

So is this information deliberately not shown in Make? With some compiler -WnoXXX?

Tracked down some of them just for fun and edited the source code to eliminate them.
Fixing them all would probably be unproductive donkey work.
