* Require Autoconf 2.50.

  Rationale: Older versions set YYTEXT_POINTER wrong in config.h for nearly
  all non-Linux platforms resulting in a build failure.
  Note to developers: you either need to install your own autoconf or run
  autogen.sh on a Debian Woody platform (which has a hybrid 2.13/2.52
  installation of Autoconf, choosing 2.13 by default and 2.52 if AC_PREREQ
  asks for it.  Sorry.
