x86 unit
Intel X86 specific routines for Unix platforms.
The x86 unit contains some of the routines that were present in
the 1.0.X Linux unit, and which were Intel (PC) architecture specific.
These calls have been preserved for compatibility, but should be considered deprecated: they are not portable and may not even work on future Linux versions.
