www/rubygem-hpricot: fix build with clang 16
Clang 16 has a new error about incompatible function types, which shows
up when building www/rubygem-hpricot:
fast_xs.c:165:39: error: incompatible function pointer types passing 'VALUE (VALUE)' (aka 'unsigned long (unsigned long)') to parameter of type 'VALUE (*)(VALUE, VALUE)' (aka 'unsigned long (*)(unsigned long, unsigned long)') [-Wincompatible-function-pointer-types]
array = rb_rescue(unpack_utf8, self, unpack_uchar, self);
^~~~~~~~~~~~
/usr/local/include/ruby-3.1/ruby/internal/iterator.h:364:62: note: passing argument to parameter 'r_proc' here
VALUE rb_rescue(VALUE (*b_proc)(VALUE), VALUE data1, VALUE (*r_proc)(VALUE, VALUE), VALUE data2);
^This is because the r_proc parameter of rb_rescue() should be a pointer
to a function taking two VALUE parameters, not one (the second parameter
can contain an exception to be handled).
Another similar error occurs later in hpricot_scan.c, which was
generated from hpricot_scan.rl:
hpricot_scan.rl:855:3: error: incompatible function pointer types passing 'VALUE (VALUE, VALUE, VALUE, VALUE, VALUE)' (aka 'unsigned long (unsigned long, unsigned long, unsigned long, unsigned long, unsigned long)') to parameter of type 'VALUE (*)(VALUE, VALUE, VALUE, VALUE)' (aka 'unsigned long (*)(unsigned long, unsigned long, unsigned long, unsigned long)') [-Wincompatible-function-pointer-types]
rb_define_singleton_method(mHpricot, "css", hpricot_css, 3);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/usr/local/include/ruby-3.1/ruby/internal/anyargs.h:307:143: note: expanded from macro 'rb_define_singleton_method'
#define rb_define_singleton_method(obj, mid, func, arity) RBIMPL_ANYARGS_DISPATCH_rb_define_singleton_method((arity), (func))((obj), (mid), (func), (arity))
^~~~~~
/usr/local/include/ruby-3.1/ruby/internal/anyargs.h:270:1: note: passing argument to parameter here
RBIMPL_ANYARGS_DECL(rb_define_singleton_method, VALUE, const char *)
^This is because the func parameter of rb_define_singleton_method()
should be a pointer to a function taking four VALUE parameters, not five.
