compilers/d: Add b_ndebug support D lang compilers have an option -release (or similar) which turns off asserts, contracts, and other runtime type checking. This patch wires that up to the b_ndebug flag. Fixes #7082 5 years ago			`# Copyright 2016 The Meson development team`

Fix destdir_join The old implementation assumed a path is of Windows iff the second character is a colon. However, that is not always true. First, a colon can be included in a non-Windows path. For example, it is totally fine to have a directory named ':' on Linux 5.17.0 tmpfs. Second, a Windows path may start with \\ for UNC or extended length. Use pathlib to handle all of these cases. 2 years ago			`from pathlib import PurePath`

simplify destdir_join for readability We can immediately short-circuit if there is no destdir, as we simply return the prefix unchanged. If there is some kind of destdir and the prefix contains a drive letter, then no matter what we need to remove the drive letter before joining. Technically, if the destdir is a relative path e.g. `destdir\` and `C:\prefix`, we should still install to `destdir\prefix` without the drive letter. But... we also guarantee that destdir is an absolute path (or empty) anyway. And even if we didn't, non-absolute destdir is a broken concept for a variety of complicated reasons. So none of this matters in practice. One way or another, we don't need to actually check whether destdir is an absolute path before cutting off the prefix drive letter. 3 years ago			`if not d1:`
