it also works on file names with special characters.


Build-tools/Do-compile:
  Ever and again, some test creates a file name with special characters that need to be
  escaped when passed to the shell; as this is not done, 'system("rm -f ...");' fails
  on them, the old test tree is not deleted, and the build fails.
  Prevent this by changing to Perl 'unlink()' which does not need escaping.

  Add -DDBUG_ON to CXXFLAGS whenever it is added to CFLAGS.
  Thus, sql/ha_innodb.cc will be compiled with the same
  setting of UNIV_DEBUG as the rest of InnoDB,
  i.e., --with-debug enables InnoDB ut_ad() assertions
  everywhere.
