4014    This section tries to collect knowledge about common headers, and the
4015    problem they cause.  By definition, this list will always require
4016    additions.  Please help us keeping it as complete as possible.

4019    @item @file{inttypes.h} vs. @file{stdint.h}
4020    Paul Eggert notes that: ISO C 1999 says that @file{inttypes.h} includes
4021    @file{stdint.h}, so there's no need to include @file{stdint.h}
4022    separately in a standard environment.  Many implementations have
4023    @file{inttypes.h} but not @file{stdint.h} (e.g. Solaris 7), but I don't
4024    know of any implementation that has @file{stdint.h} but not
4025    @file{inttypes.h}.  Nor do I know of any free software that includes
4026    @file{stdint.h}; @file{stdint.h} seems to be a creation of the committee.
