source: rtems/configure.in @ 2c3840b

Last change on this file since 2c3840b was 2c3840b, checked in by Joel Sherrill <joel.sherrill@…>, on 09/30/98 at 20:58:39

Added new autoconf test for i386 code16/code32 support. The guts of the
test were suggested by Ian Taylor <ian@…> and Joel did the
hard part of putting it in aclocal and editting all the offending
Makefiles and source code which could use this feature.
