Provide i386 versions of div and ldiv -- they are simpler than the C versions, since the idiv instruction does the right thing wrt truncating towards zero. 1993-10-09 02:57:13 +03:00			`/*`

Change instances of LIBC_RCS back to LIBC_SCCS. If we are going to change th LIBC_RCS, the entire source tree should be updated at once. Remove && !defined(lint) from conditionals around rcs id's. No one is ever going to pass a *.s file through lint. 1993-10-21 04:39:55 +03:00			`#if defined(LIBC_SCCS)`
