- Tor Arntsen brought some info about SGI IRIX:

  IRIX supports 3 different executable/object formats, -32, -n32 and -64.

  -n32 is default 32-bit format, -32 is the "old" 32-bit format, and -64 is

  the 64-bit format.  Libraries for the different formats are in lib, lib32

  and lib64 respectively.

  We've now adjusted the configure script to adapt to this when scanning for

  3rd party libs, such as OpenSSL.
