stdint module on SGI

[Mark D. Baushke]

Hi Bruno,

The following two patches take a closer step toward making things work
under the default c89 compiler on SGI boxes.

All files that #include <stdint.h> still get warnings like this one:

cc-1035 cc: WARNING File = /usr/include/stdint.h, Line = 5
  #error directive:  This header file is to be used only for c99 mode
          compilations

  #error This header file is to be used only for c99 mode compilations
   ^

right now. It might be nice if just the existence of <stdint.h> did not
imply that it was useful to the compiler... However, I will leave that
to you for future changes.

The correct thing to include on SGI IRIX 6.5 boxes is apparently the
<inttypes.h> file which has all of the correct typedef and macro
definitions.

Given that a conforming C99 function <inttypes.h> is supposed to include
<stdint.h>, I wonder if it makes sense to try to only #include
<inttypes.h> and see if that works before attempting to try to #include
<stdint.h> along with it.
