  New Revision: 17793

  Modified files:
    branches/ruby_1_8/ChangeLog
    branches/ruby_1_8/configure.in
    branches/ruby_1_8/lib/mkmf.rb

  Log:
    * configure.in (AC_USE_SYSTEM_EXTENSIONS): instead of AC_AIX
    
    * lib/mkmf.rb (create_tmpsrc): we need to include COMMON_HEADERS,
      namely inclusion of ruby.h, because _GNU_SOURCE is now defined
      	  there (if any) and socket.so requires it on Linux systems.
