New Revision: 1118

Modified:
   trunk/Makefile
   trunk/code/qcommon/vm_ppc.c
   trunk/code/unix/unix_main.c
   trunk/code/unix/unix_net.c
Log:
* (bug 3268) Replace Mac OS X Carbon API calls with native ones (thanks
             to i3enedek).
* remove some spammy Mac OS X printf's regarding local network detection
* replaced a #warning for non-OS X PPC systems with a call to
  msync(..., MS_INVALIDATE).  This needs testing.
