   1 /* This file permits building Emacs with a shared libc on Sunos 4.
   2    To make this work, you must completely replace your C shared library
   3    using one of the SunOS 4.1.x jumbo replacement patches from Sun.
   4    Here are the patch numbers for Sunos 4.1.3:
   5    100890-10   SunOS 4.1.3: domestic libc jumbo patch
   6    100891-10   SunOS 4.1.3: international libc jumbo patch  */
