Patch 7.4.174
Problem:    Compiler warnings for Python interface. (Tony Mechelynck)
Solution:   Add type casts, initialize variable.
Files:      src/if_py_both.h

In incremental build for patches 173-175 I get the following:

- In tiny build but not in huge build:

gcc -c -I. -Iproto -DHAVE_CONFIG_H -I/usr/local/include -O2 -fno-strength-reduce -Wall -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=1 -o objects/move.o move.c
move.c: In function ‘scroll_cursor_halfway’:

- In huge build (tiny build has no Python):
