__fpscr_values 問題 †

||||||||||||||||||||||||||||||||||||||
| 案 | グループ | パッチなど | Shard lib 互換性 | 備考(etchではどうすべきか？) | ||

| 案0 | GLIBC_2.2 | GLIBC_2.2パッチ | ◎ | ◎ | ○？ | 用いない方向。案1,2環境で作成したshared libをリンク可能（グループ情報が含まれないため） |
| 案1 | GLIBC_PRIVATE | CVS-fpscr_valuesパッチのみ | △ | ◎ | ○? | 案1は、特に副作用は無いらしい。案2はグループ無しであるが問題ないらしい。「案1と案3は同じグループであるため、互換性が高い」というならば、積極的に案1を採用すべきだが、そういった利点がないなら案2を採用するのが無難 |
| 案2 | グループなし | glibc-2.3.5そのまま | △ | ◎ | ○? | |
| 案3 | GLIBC_PRIVATE | glibc-2.3.5-branch update-20050722 audit function込み？ | △? | ◎? | ◎ | 将来バージョン。下位互換性は考慮されていると推測。ただし、枯れてない可能性がある。またdebianとの相性問題も心配 |

作るか作らないかは気分しだいです。(笑)
debian26版のglibcではどうなっているかというと！
