warning: type specifier missing, defaults to 'int'

[Ryan Carsten Schmidt]

These warnings occur when compiling vtwm 5.5.0 on macOS 12 with Apple Clang 14:

add_window.c:460:12: warning: type specifier missing, defaults to 'int' [-Wimplicit-int]
    static lastwingroup = 0;
    ~~~~~~ ^
add_window.c:461:12: warning: type specifier missing, defaults to 'int' [-Wimplicit-int]
    static lastwin = 0;
    ~~~~~~ ^
add_window.c:462:12: warning: type specifier missing, defaults to 'int' [-Wimplicit-int]
    static lasttime = 0;
    ~~~~~~ ^

Newer compilers like llvm.org clang 18 consider this to be an error, not a warning:

add_window.c:460:12: error: type specifier missing, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int]
  460 |     static lastwingroup = 0;
      |     ~~~~~~ ^
      |     int
add_window.c:461:12: error: type specifier missing, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int]
  461 |     static lastwin = 0;
      |     ~~~~~~ ^
      |     int
add_window.c:462:12: error: type specifier missing, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int]
  462 |     static lasttime = 0;
      |     ~~~~~~ ^
      |     int

To fix it, add int after each static.
