Patch installed to fix two bootstrap failures

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

	I had some trouble bootstrapping using OSF4 cc:

 > cc -c -DIN_GCC -DHAIFA -g -DHAVE_CONFIG_H -I. -I. -I./config
 > 	-I./../include cppfiles.c
 > cc: Warning: cppfiles.c, line 863: In this statement, the referenced
 > 	type of the pointer value "xrealloc(...)" is "signed char", which is
 > 	not compatible with "unsigned char".
 >           buf = xrealloc (buf, len);
 > ----------^
 > cc: Warning: cppfiles.c, line 992: In this statement, the referenced
 > 	type of the pointer value "xrealloc(...)" is "signed char", which is
 > 	not compatible with "unsigned char".
 >           buf = xrealloc (buf, len);
 > ----------^
 > cc: Error: cppfiles.c, line 1000: In this statement, "buf" and

 >   fp->buf = (len - offset < 20) ? buf : xrealloc (buf, op - buf);
 > ------------^
 > make[2]: *** [cppfiles.o] Error 1


	So I installed the following patch which fixes the two
warnings and the one error.  I also fixed a problem in cppinit.c for
SunOS4 cc.

+	* cppfiles.c (read_and_prescan): Cast the result of `xrealloc' to
+ 	U_CHAR* when assigning to one.  Ensure the values of a ?: operator
+ 	have the same type.
+
+	* cppinit.c (initialize_char_syntax): Use K&R function definition.
