/* Definitions for Intel 386 running Interactive Unix System V,
producing stabs-in-coff output (using a slightly modified gas).
Specifically, this is for recent versions that support POSIX;
for version 2.0.2, use configuration option i386-sysv instead. */

system-independent change there, I override dbxout.c's defaults.
Perhaps it would be better to use ".Ltext0" instead of
`ltext_label_name', but we've already generated the label, so we just
use it here. --karl@cs.umb.edu */
