call: Fix structure mismatch

GCC with LTO enabled warn:

/bin/sh ../libtool  --tag=CC   --mode=link gcc  -O2 -Wall -flto   -o call call.o menu.o crc.o yapp.o dostime.o -lncursesw -lax25
libtool: link: gcc -O2 -Wall -flto -o call call.o menu.o crc.o yapp.o dostime.o  -lncursesw -lax25
menu.h:22:9: warning: type of 'winopen' does not match original declaration [-Wlto-type-mismatch]
 WINDOW* winopen(wint*, int, int, int, int, int);
         ^
menu.c:20:9: note: 'winopen' was previously declared here
 WINDOW *winopen(wint * wtab, int nlines, int ncols, int begin_y,
         ^
menu.c:20:9: note: code may be misoptimized unless -fno-strict-aliasing is used

This was caused by different .c files being built with different libc
 feature selection macros.  Adding

  #define _DEFAULT_SOURCE
  #define _XOPEN_SOURCE
  #define _XOPEN_SOURCE_EXTENDED

to menu.c would have been sufficient but it seems good practice to add
the same definition to all .c files.
