Another IRIX build problem

[Patrick Baggett]

When compiling Erlang on IRIX with MIPSpro 7.4.4, I get:

cc-1196 c99: WARNING File = memsup.c, Line = 460
  The indicated function is declared implicitly.

      if (get_extended_mem_sgi(me))     return;
          ^

The reason is that the prototype's definition in the same file is surrounded
by #if defined(__sgi__), and it needs to be changed to __sgi. Can anyone
push this quick fix?
