'st_check_for_sizeof_st_index_t' declared as array with a negative size (emscripten)

Description
Compilation of st.h with Emscripten 1.38.30 fails:
st.h:65:45: error: 'st_check_for_sizeof_st_index_t' declared as an
array with a negative size
typedef char st_check_for_sizeof_st_index_t[SIZEOF_VOIDP == (int)sizeof(st_index_t) ? 1 : -1];
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3rdparty/edbee-lib/vendor/onig/config.h:109:22: note: expanded from macro 'SIZEOF_VOIDP'
#define SIZEOF_VOIDP 8
^
1 error generated.
shared:ERROR: compiler frontend failed to generate LLVM bitcode, halting
Makefile:36871: recipe for target 'regcomp.o' failed
Both sizeof are set to 8:
onig$ cat config.h | grep SIZEOF_LONG
#define SIZEOF_LONG 8
#define SIZEOF_LONG_LONG 8
Is there a way to fix this issue or add a workaround for emscripten (__EMSCRIPTEN__
)?

What is this file?
Do you mix different oniguruma?
Original discussion at here: https://github.com/k-takata/Onigmo/issues/130
I think it's better to fix this in Ruby rather than in Onigmo.
I can suggest two ways.
1. Add #ifndef
around st_check_for_sizeof_st_index_t
--- a/include/ruby/st.h
+++ b/include/ruby/st.h
@@ -55,7 +55,9 @@ typedef st_data_t st_index_t;
typedef int st_compare_func(st_data_t, st_data_t);
typedef st_index_t st_hash_func(st_data_t);
+#ifndef __EMSCRIPTEN__
typedef char st_check_for_sizeof_st_index_t[SIZEOF_VOIDP == (int)sizeof(st_index_t) ? 1 : -1];
+#endif
#define SIZEOF_ST_INDEX_T SIZEOF_VOIDP
struct st_hash_type {
2. Remove st_check_for_sizeof_st_index_t
The size of void*
and long
or long long
are already checked at here:
https://github.com/ruby/ruby/blob/8c6f1715f03e0322c96d614a42c30bee0b7790eb/include/ruby/st.h#L21-L27
Checking the size of st_index_t
might be redundant.
