  New Revision: 59939

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=59939

  Log:
    ext/date/extconf.rb: check for timezone and altzone
    
    Instead of in configure.in. As of r28592 the HAVE_VAR_TIMEZONE and
    HAVE_VAR_ALTZONE macros are only used by ext/date. ext/date doesn't care
    whether they are int or long, so just check for the existence.
