    The Homebrew and MinGW versions of glib no longer suffer from this.
    This is apparently impossible to fix as long as we do not
    have control over the regex engine build.

    It would also directly allow globbing by tweaking the syntax.
    TRE also looks promising and is smaller than Oniguruma.
    GRegEx (PCRE) could still be supported as a fallback.
