It is also needed to use -Wall. Both arguments to strspn () are constants, so
in this case the __builtin_strspn () is used. You shouldn't see this warning
with -fno-builtin-strspn. Thus <string.h> is correct in this regard.
GCC 4.[1-5] are without warnings, with 4.6 I get:
/home/marek/rh/tests/pr54486.c: In function ‘main’:
/home/marek/rh/tests/pr54486.c:7:5: warning: format ‘%zu’ expects argument of
type ‘size_t’, but argument 2 has type ‘long unsigned int’ [-Wformat]
/home/marek/rh/tests/pr54486.c:8:5: warning: format ‘%zu’ expects argument of
type ‘size_t’, but argument 2 has type ‘long unsigned int’ [-Wformat]
with 4.7/trunk:
/home/marek/rh/tests/pr54486.c: In function ‘main’:
/home/marek/rh/tests/pr54486.c:7:5: warning: format ‘%zu’ expects argument of

/home/marek/rh/tests/pr54486.c:8:5: warning: format ‘%zu’ expects argument of
