This doesn't look doable to me, or at least such little more elegant output is very pricey. First of all, mingw is just one of the dozen compilers hbmk2 currently supports. hbmk2 would need error output parsers for each of them (think about multiple message format across different compiler versions to make it even more difficult to maintain). Then it would have to know a way to determine original .prg source name based on object name. This is sometimes easy to guess (it's guessing nevertheless), but not easily doable in a generic way (f.e. .clp files, or objects included in libs, which have the same name as .prg files in actual project, multiple phase builds using -hbcmp and friends, .c source objects, objects in libs, inline .c). Suppose we have the .prg source name, then comes the impossible part: Finding the occurrences of symbol in source code. Granted, hbmk2 could do a simple string search (if managed to reach this point), but this isn't too much added value compared to a simple 'grep' issued by user. To do it properly though, it would need serious compiler/pp support. So overall I see not much chance this could make into hbmk2, or any similar tool. Of course if someone has better ideas how to solve this problem, I'm interested to hear it.
