gdb 4.17 AIX SIGWINCH warning fix

[Philippe De Muyter]

The last warning fix for gdb-4.17 on AIX 4.1.5 :
With xlc :
	"gdb/top.c", line 1953.21: 1506-280 (W) Function argument assignment
	between types "void(*)(int)" and "void(*)(void)" is not allowed.
With gcc :
	gdb/top.c: In function `init_signals':
	gdb/top.c:1953: warning: passing arg 2 of `signal' from incompatible
	pointer type

Fri May  1 06:42:14 1998  Philippe De Muyter  <phdm@macqel.be>

	* config/xm-aix4.h (SIGWINCH_HANDLER): Function `aix_resize_window'
	must accept a signal number as parameter.
	* config/rs6000/xm-rs6000.h (SIGWINCH_HANDLER): Ditto.
	* utils.c (initialize_utils): Give a parameter to `SIGWINCH_HANDLER'.
