New Revision: 3670

Modified:
   liboggz/trunk/configure.ac
   liboggz/trunk/src/tools/oggz-chop/httpdate_test.c
Log:
MacOS X 10.4 only defines timezone with _XOPEN_SOURCE. Check for this.

This is timezone the global variable, not the function, used by 
httpdate.c. Always defining _XOPEN_SOURCE directly in the requisite
files is another option, and probably safe.
