Fixed 3 major failures in this test:

  1. Tests work better when they are actually run..
  2. When file is opened, it should be closed sometime too.
  3. AC_TRY_RUN cleans after itself (rm -f conftest.*), so it's
     good idea to read the values while the file still exists.

#
# James, TEST BEFORE YOU COMMIT!!!!!!!
#
# Andi, I get these results (in Linux/i386):
#
#  ZEND_MM_ALIGNMENT      4
#  ZEND_MM_ALIGNMENT_LOG2 2
#
# Weren't these supposed to be 8 and 3 ?
