[benjaminp]

You probably need to define it to be "ll".

[JeffreyWalton]

You probably need to define it to be "ll".

Ah, OK. It was tricky trying to pass in a quoted string *with* the quotes to the preprocessor without the stringify stuff. I found it easier to open the file and just hard code what was needed.

Thanks again for the help.

If a stable version fails to build within a modern environment that has everything installed, then according to my understanding

THERE IS A BUG

That is to say, the current resolution, "not a bug", does not match with my understanding of this world. The whole console output is at the attached file, but here's an excerpt:
