[patch] nto target update

[Aleksandar Ristovski <ARistovski@qnx.com>]

[-- Attachment #1: Type: text/plain, Size: 608 bytes --]

Nto target has been maintained in our private branch and hasn't been
synchronized with mainstream for a while.
As a result, nto target does not compile. This patch brings it up-to date.

Thank you,

Aleksandar Ristovski



ChangeLog:

2007-11-07  Aleksandar Ristovski <aristovski@qnx.com>

	Update for nto target.

	* i386-nto-tdep.c: Update.
	* nto-procfs.c: Update.
	* nto-tdep.c: Update.
	* nto-tdep.h: Update.
