Just did a clone of the dev branch. This is the output I got when I did a make. Don't know if this is a problem or not.

Don, can you tell me what version of gcc you're using? (gcc --version)
I'm using 10.2.1 and I'm not seeing the warnings that you are getting.
In looking at that line of code, it shouldn't even be complaining. "~"
isn't a directive, it's a string literal. The result of the sprintf
(which really should be an snprintf) is going to be something along the
lines of /some/pathname/~0 (or 1)

tnx.

You might want to reach out to the gcc maintainers and let them know they
might have a bug on their hands. The parser shouldn't be interpreting a
string literal as an operator.
