Description

When trying to compile the latest version of Ruby, I get a lot of warnings such as the following:

compiling array.c
In file included from transient_heap.h:12:0,
                 from array.c:21:
array.c: In function ‘rb_ary_uniq_bang’:
internal.h:766:74: warning: signed and unsigned type in conditional expression [-Wsign-compare]
 #  define RHASH_SIZE(h)      (RHASH_ARRAY_P(h) ? RHASH_ARRAY_SIZE_RAW(h) : RHASH_ST_SIZE(h))
                                                                                                                              ^
array.c:4864:17: note: in expansion of macro ‘RHASH_SIZE’
     hash_size = RHASH_SIZE(hash);
                 ^

I have attached a longer list in a file.

The version of Ruby I used for compilation is ruby 2.4.0dev (2016-06-09 trunk 55334) [x86_64-linux], but that should be unrelated.
