Likewise, this caused problems for coverage testing, where relative paths weren’t correctly interpreted by LCOV, hence this change to embed absolute paths: . > One could instead embed the absolute path, but then you have the problem > that you might remove your build or source directory; it doesn't make > sense to have installed files pointing to build paths.

As noted in the other thread, I’d rather get rid of this fluid and have ‘compile’ & co. call ‘canonicalize-path’. Thanks, Ludo’.
