Linux下多平台编译器GCC v4.4.0 稳定版发布

Linux系统下的Gcc（GNU C Compiler）是GNU推出的功能强大、性能优越的多平台编译器，是GNU的代表作品之一。gcc是可以在多种硬体平台上编译出可执行程序的超级编译器，其执行效率与一般的编译器相比平均效率要高20%~30%。 Gcc编译器能将C、C++语言源程序、汇程式化序和目标程序编译、连接成可执行文件，如果没有给出可执行文件的名字，gcc将生成一个名为 a.out的文件。在Linux系统中，可执行文件没有统一的后缀，系统从文件的属性来区分可执行文件和不可执行文件。而gcc则通过后缀来区别输入文件的类别。

Changes:

Many optimizer improvements were made. Version 3.0 of the OpenMP specification is now supported for the C, C++, and Fortran compilers. "Uninitialized" warnings do not require enabling optimization anymore. The experimental support for the upcoming ISO C++ standard C++0x was improved. Several new targets and target specific improvements were introduced, www.britepic.org , while several old targets were obsoleted or removed. Many bugs were fixed.
