Bug #12397: Since r54986, syntax error with Oracle Solaris Studio 12.x on Solaris 10

• Status: Closed
• Assignee: -
• Target version: -
• Backport: 2.1: DONTNEED, 2.2: DONTNEED, 2.3: DONTNEED

[ngoto (Naohisa Goto)]

r54986以降、Solaris 10上の Oracle Solaris Studio 12.3 および 12.4 にて、以下のエラーでコンパイルに失敗します。

一部分のみピックアップすると、extension が単なる関数扱いされているのが原因のようです。

"array.c", line 2031: warning: implicit function declaration: __extension__ (E_NO_IMPLICIT_DECL_ALLOWED)
"array.c", line 2031: syntax error before or at: {

Oracle Solaris Studio 12.x には、__builtin_constant_p() は存在するため、HAVE_BUILTIN___BUILTIN_CONSTANT_P は 1 になります。
https://docs.oracle.com/cd/E19205-01/821-2496/gipib/index.html

しかし、extension は存在しません。（GCC拡張？）

configureで __builtin_constant_p をチェックするだけではなく、 extension の有無もチェックする必要があるのかもしれません。

以下、詳細なエラーメッセージ。

• Status changed from Open to Closed

Applied in changeset r55082.

---

Use RB_GNUC_EXTENSION_BLOCK instead of extension

• include/ruby/defines.h (RB_GNUC_EXTENSION, RB_GNUC_EXTENSION_BLOCK):
  macros for skipping extension on non-GCC compilers.
• eval_error.c (warn_print): use RB_GNUC_EXTENSION_BLOCK instead of
  extension because extension is a GNU extension.
  Fix compile error on Solaris 10 with Oracle Solaris Studio 12.x.
  [Bug #12397] [ruby-dev:49629].
• internal.h (rb_fstring_cstr, rb_fstring_enc_cstr): ditto
• include/ruby/encoding.h (rb_enc_str_new, rb_enc_str_new_cstr): ditto
• include/ruby/intern.h (rb_str_new, rb_str_new_cstr,
  rb_usascii_str_new, rb_utf8_str_new, rb_tainted_str_new_cstr,
  rb_usascii_str_new_cstr, rb_utf8_str_new_cstr,
  rb_external_str_new_cstr, rb_locale_str_new_cstr,
  rb_str_buf_new_cstr, rb_str_cat_cstr, rb_exc_new_cstr): ditto

r55084 にて、symbol.h 内の __builtin_constant_p についても、同様に措置しました。
（元々 r54986 の修正から漏れていた？）
