----------------------------------------
ext/digest については r49564 以降、 ext/openssl については r55285 以降、
Solaris 10 上の Oracle Solaris Studio 12.x によるコンパイル時に以下のwarningが出ます。

```
compiling md5init.c
"md5ossl.h", line 11: warning: syntax error:  empty declaration (E_EMPTY_DECLARATION)
（略）
compiling sha1init.c
"sha1ossl.h", line 18: warning: syntax error:  empty declaration (E_EMPTY_DECLARATION)
（略）
compiling sha2init.c
"sha2ossl.h", line 23: warning: syntax error:  empty declaration (E_EMPTY_DECLARATION)
"sha2ossl.h", line 24: warning: syntax error:  empty declaration (E_EMPTY_DECLARATION)
"sha2ossl.h", line 25: warning: syntax error:  empty declaration (E_EMPTY_DECLARATION)
（略）
compiling ossl_pkey_rsa.c
"ossl_pkey_rsa.c", line 659: warning: syntax error:  empty declaration (E_EMPTY_DECLARATION)
"ossl_pkey_rsa.c", line 660: warning: syntax error:  empty declaration (E_EMPTY_DECLARATION)
"ossl_pkey_rsa.c", line 661: warning: syntax error:  empty declaration (E_EMPTY_DECLARATION)
```

原因は [Bug #12470] とほぼ同様です。つまり、マクロ使用時の最後のセミコロンが余計で、何も内容の無い行が発生して、empty declaration の警告が出ています。
