That may be safe, I haven't checked, but in any case it is very ugly.
Please do not use m4_esyscmd unless it cannot be helped at all, it's
an ugly crutch and will only lead to problems.

You can use
  m4_foreach_w([my_file], [autoconf autoheader ...],
               [AC_CONFIG_FILES([my_file], [chmod +x my_file])])

to have less to type.  Note the expanded configure script doesn't grow
all that huge either, it adds at most a couple of lines per file.

Cheers,
