gno/bin/date/modsleep.asm
gdr-ftp 98f457ebec Initial checkin of asm version 1.0 of date(1) by Phil Vandry (no changes
for GNO v2.0.6).  I've not checked, but it's unlikely that this is
POSIX compliant.

* Modified sleep routine based on sleep in libgno
* It was necesary to disassemble this routine and reassemble it so that
* date.asm can use its private variables. It needs to do this to make
* date abort when it is in the middle of a sleep()
