autoconf/tests/mktests.sh
Paul Eggert 39572957c6 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
Prefer 'sort -u' to 'sort | uniq'.  Filter data before sorting it.
Use 'comm' rather than N instances of grep; this also fixes a bug
whereby substrings were incorrectly matched, causing us to not
generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
(exclude_list): Exclude empty macros.
(ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
