    Fixing signedness warning in glib/gfileutils.c
    
    glib/gfileutils.c: In function ‘write_to_file’:
    glib/gfileutils.c:1176:19: error: comparison of integer expressions of different signedness: ‘gssize’ 
{aka ‘long int’} and ‘gsize’ {aka ‘long unsigned int’} [-Werror=sign-compare]
     1176 |       g_assert (s <= length);
          |                   ^~
    glib/gmacros.h:939:25: note: in definition of macro ‘G_LIKELY’
      939 | #define G_LIKELY(expr) (expr)
          |                         ^~~~
    glib/gfileutils.c:1176:7: note: in expansion of macro ‘g_assert’
     1176 |       g_assert (s <= length);
          |       ^~~~~~~~
