Not to my knowledge. I was aware of its existence, but since its
license does not allow commercial use and one of the things I do with
Mercury is develop commercial software there didn't seem any compelling
reason to look into it further.

Just so you're aware: there's bit more to it than just doing
$ ./configure --with-cc=ccomp
If you search the git repository for when we added support for clang**
(circa 2011), that might give you some idea of what is required to use
a new C compiler.
The obvious starting point is: can you successfully compile the Boehm
GC with it?
