I saw:

 ../../src/gdb/ada-typeprint.c: In function 'void print_fixed_point_type(type*, ui_file*)':
 ../../src/gdb/ada-typeprint.c:366: warning: passing 'float' for argument 2 to 'DOUBLEST ada_fixed_to_float(type*, LONGEST)'

 ../../src/gdb/value.c: In function 'LONGEST unpack_long(type*, const gdb_byte*)':
 ../../src/gdb/value.c:2833: warning: converting to 'LONGEST' from 'DOUBLEST'
 ../../src/gdb/value.c:2838: warning: converting to 'LONGEST' from 'DOUBLEST'

gdb/ChangeLog:
yyyy-mm-yy  Pedro Alves  <palves@redhat.com>

	* ada-typeprint.c (print_fixed_point_type): Don't pass float as
	argument to function expecting LONGEST.
	* value.c (unpack_long): Add casts to LONGEST.
