+  You can build a 64-bit executable (with larger maximum buffer size)
+  on Irix 6.5 by specifying the 64-bit ABI using the `-64' compiler
+  flag or otherwise (see cc(1)).  This may work on earlier Irix 6
+  systems if you edit src/s/irix6-0.h following irix6-5.h.

   The 19.26 pretest was reported to work on IRIX 4.0.5 and 5.2.
   19.23 was reported to work on IRIX 5.2, but you may need to install
   the "compiler_dev.hdr.internal" subsystem in order to compile unexelfsgi.c.

   As of version 2.95, GCC doesn't support the 64-bit ABI properly, but
   later releases may.
