Subject: [PATCH] Be prepared for a case-insensitive file system on Linux, too,
 not just macOS

Can easily happen at least on WSL.

Also avoid warnings about the deprecated readdir_r(). In current
POSIX, readdir() is required to be thread-safe. (It might well have
been for a long time in those POSIXish platforms we care for, I don't
know.)
