#1 Support newer OS.

[Takahiro Kambe]

Hi,

Ruiby-quota dosen't compile on newer operating systems. Here is a patch to fix these problem.

* Compile problem on NetBSD 4.0 and later.
* Compile problem on DragonFly BSD.
* Compile problem on Linux 2.6.x.
* Module's version is still "0.4.1" although this extention module's version os "0.5.1".
* Portability fix in rb_quotactl().

Attached patch would be fix these problems.

Best regards.
