-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 According to Philip Prindeville on 7/15/2008 12:22 AM: | | Well, it kind of begs the question: if ac_sizeof_long_long_int != | ac_sizeof_long_long_unsigned_int, then what happens when you assign a | LONGLONG_MAX to a signed long long, and then copy that into an unsigned | long long, or vice versa... At one point, I proposed modifying autoconf to require both types, or else claim that neither type exists, because there was an actual platform (Tandem/NSK) reported by Matthew Woehlke that actually had 32-bit unsigned long long and 64-bit long long. Paul Eggert declined the idea at the time, but perhaps it needs revisiting? At any rate, M4 gives an example of how to do this: http://git.savannah.gnu.org/gitweb/?p=m4.git;a=commitdiff;h=7db3ae3 |> |> If <stdint.h> and <inttypes.h> were available everywhere then much of |> this gobbly gook could go away. Maybe in another 10 years or so that |> will be the case. You may want to consider using gnulib, which provides a replacement <stdint.h> and <inttypes.h> and takes care of all of the type definitions in those two headers (it does not yet provide a <sys/types.h> replacement, with additional useful types). - -- Don't work too hard, make some time for fun as well!
