[nto target] Fix compiler warnings.

[Aleksandar Ristovski <aristovski at qnx dot com>]

Hello Ulrich,

Instead of extensive patch I tried last time, this one is simple and merely fixes compiler warnings (I get the warnings with gcc 4.2.*). 

Note that the type-punned pointer warning is fixed in a simpler way (as opposed to union I did the last time).

Please review.

Thanks,

Aleksandar


ChangeLog:

2008-07-22  Aleksandar Ristovski  <aristovski@qnx.com>

	* nto-procfs.c (procfs_xfer_memory): Changed signature.
	(procfs_resume): Workaround for dereferencing type-punned pointer
	warning.
	* nto-tdep.c (nto_parse_redirection): Change signature to be const 
	correct.
	* nto-tdep.h (nto_parse_redirection): Likewise.
