Warnings shouldn't stop the compile process. Are there any error
messages as well?

in C++, you can assign integer values to a char. For instance, if you
wanted to make "char retVal" equal a space, you could set it with

retVal = 32; //or
retVal = ' ';

I'm not sure why this would stop a compile, though.

Interesting warning message. It looks good to me off the top of my
head. strcmp() should be able to return possitive, 0, or negative. Are
there any error messages around this, or is it only the warning?
