Agreed. I'm adding this verification so we get notified when the case of
a 64-bit 'int' appears for real.

OK, my argument was not good. A better argument is: If our replacement
<stdint.h> includes simply <inttypes.h>, not @ABSOLUTE_INTTYPES_H@, then
a simple
          #include <stdint.h>
will do the wrong thing: It will

   - start including our stdint.h,
   - include the system's stdint.h,
   - start including our inttypes.h,
     - include the system's inttypes.h,
     - include our stdint.h, but this has no effect due to the double-inclusion
       guard,
     - go on testing various macros like UINT32_MAX or INT64_MAX
       which have not been defined yet!
   - end including our inttypes.h,
   - define the various *_MIN and *_MAX macros
   - end including our stdint.h.

Whereas if our replacement <stdint.h> includes @ABSOLUTE_INTTYPES_H@, the
sequence of events is this:

   - start including our stdint.h,
   - include the system's stdint.h,
   - start including the system's inttypes.h,
     - possibly: include our stdint.h, but this has no effect due to the
       double-inclusion guard,
   - end including the system's inttypes.h,
   - end including our stdint.h.

I'm adding a comment like this.

I agree for the first half of the code. In the second half, the original
code with "- denom" is safer than your proposed code with "- result.rem" -
because here it could be result.rem which is == INTMAX_MIN. But thanks for
having noticed this; I don't usually view a unary minus as a dangerous
operation :-)


So here's the patch I'm committing.

2006-08-26  Bruno Haible  <address@hidden>

        * modules/inttypes (Files): Add lib/inttypes_.h, remove lib/inttypes.h.

        * lib/stdint_.h: Include <inttypes.h> through its absolute filename.
        * m4/stdint.m4 (gl_STDINT_H): Define also ABSOLUTE_INTTYPES_H.
        * modules/stdint (Makefile.am): Substitute also ABSOLUTE_INTTYPES_H.
