dnl quote from SunOS-5.8 sys/inttypes.h:
|
|
dnl Use at your own risk. As of February 1996, the committee is squarely
|
|
dnl behind the fixed sized types; the "least" and "fast" types are still being
|
|
dnl discussed. The probability that the "fast" types may be removed before
|
|
dnl the standard is finalized is high enough that they are not currently
|
|
dnl implemented.
