That would seem to be

    lilypond-book: Textwidth detection with included file (issue 3136).
    
    Fix the automatic textwidth detection performed by lilypond-book.
    This failed for lytex files that include an external file in the
    preamble, when such file was compiled in an --output directory
    different from the working directory, because then the included
    file was missing. We use TEXINPUTS to let the latex process know
    where to look for input files.

later "improved" by

    Issue 3467: lilypond-book 2.17.21 and spaces in file path


Versions 2.17.17 and 2.17.24, respectively.  Instead one probably needs
to manipulate the environment directly.  No idea how sticky that is.

Actually, it would appear that working with subprocess.Popen would be
called for here.  The respective coode seems to be:
    progress (_ ("Running `%s' on file `%s' to detect default page settings.\n")
              % (global_options.latex_program, tmpfile))
    cmd = 'TEXINPUTS="%s:$TEXINPUTS" %s %s' \
        % (global_options.input_dir, global_options.latex_program, tmpfile)
    debug ("Executing: %s\n" % cmd)
    run_env = os.environ.copy()
    run_env['LC_ALL'] = 'C'

    ### unknown why this is necessary
    universal_newlines = True
    if sys.platform == 'mingw32':
        universal_newlines = False
        ### use os.system to avoid weird sleep() problems on
        ### GUB's python 2.4.2 on mingw
        # make file to write to
        output_dir = tempfile.mkdtemp()
        output_filename = os.path.join(output_dir, 'output.txt')
        # call command
        cmd += " > %s" % output_filename
        returncode = os.system(cmd)
        parameter_string = open(output_filename).read()
        if returncode != 0:
            warning (_ ("Unable to auto-detect default settings:\n"))
        # clean up
        os.remove(output_filename)
        os.rmdir(output_dir)
    else:
        proc = subprocess.Popen (cmd,
            env=run_env,
            universal_newlines=universal_newlines,
            shell=True,
            stdout=subprocess.PIPE, stderr=subprocess.PIPE)
        (parameter_string, error_string) = proc.communicate ()
        if proc.returncode != 0:
            warning (_ ("Unable to auto-detect default settings:\n%s")
                    % error_string)

And normally one should be able to do the TEXINPUTS manipulation just
like done with LC_ALL.  However, that would require looking at what goes
wrong with mingw32 here.  I have no idea what the current GUB version of
Python is.
