haiku/headers/posix/endian.h
Ingo Weinhold 2222d0559d * Introduced new header directory "config", which ATM contains HaikuConfig.h
and types.h. The idea is to provide a basic architecture/compiler
  abstraction by defining types and macros that allow the posix/ and os/
  headers to be mostly architecture/compiler agnostic. 
* Adjusted the posix/ and os/ headers accordingly.
* <SupportDefs.h>: Introduced B_PRI* and B_SCN* macros similar to the PRI*
  and SCN* macros defined in <inttypes.h>, just for the BeOS/Haiku [u]int*
  types and some POSIX types (e.g. off_t, dev_t, ino_t) that don't have POSIX
  macros. Also the B_PRI* and B_SCN* macros are available unconditionally,
  unlike the <inttypes.h> macros, which require __STDC_FORMAT_MACROS to be
  defined in C++ mode.
