Log Message:
update autoconf to 2.52. Some changes:

- Quadrigraphs
  This feature was present in autoconf 2.50 but was not documented.
  For example, `@<:@' is translated to `[' just before output.  This
  is useful when writing strings that contain unbalanced quotes, or
  other hard-to-quote constructs.
- m4_pattern_forbid, m4_pattern_allow
- Using autoscan to maintain a configure.ac.
- Fixed Fortran name-mangling and link tests on a number of systems,
  e.g. NetBSD; see AC_F77_DUMMY_MAIN, below.
- cross-compilation
  $build defaults to `config.guess`, $host to $build, and then $target
  to $host.
  Cross-compilation is a global status of the package, it no longer
  depends upon the current language.
  Cross compilation is enabled iff the user specified `--host'.
  `configure' now fails if it can't run the executables it compiles,
  unless cross-compilation is enabled.
- Cache file
  The cache file is disabled by default.  The new options
  `--config-cache', `-C' set the cache to `config.cache'.

... and many others, esp. bugfixes. Check the docs!
