GNU C Complier - GNU Compiler Collection - GCC
GNU 项目计划的主要目的是创建一个名叫 GNU’s Not Unix! (GNU) 的完全免费的操作系统。但是 GNU 在开发完全免费的操作系统上并未取得成功，直到 Linus Benedict Torvalds 开发了 Linux 操作系统，GNU 才算在免费操作系统上完成了任务。虽然 GNU 计划在开发免费操作系统上不成功，但是却成功开发著名的 GNU C Complier (GCC)。
GNU C Complier C 语言编译器执行效率高，它是自由软件发展的基石与标杆。GNU 软件还包括 GNU emacs、GNU Debugger (GDB)、GNU Bash 以及大部分 Linux 系统的程序库和工具等。
GNU C Complier (GCC) 已由最初的 C 程序语言的编译器变成了 GNU Compiler Collection (GNU 编译器套件)，The GNU Compiler Collection includes front ends for C, C++, Objective-C, Fortran, Ada, Go, and D, as well as libraries for these languages (libstdc++,…).
GNU C Complier (GCC) 重新定义为 GNU Compiler Collection (GUN 编译器套件)。
GUN 编译器套件包含多种前端处理器，以翻译各种不同语言。GCC 是一种多目标 (multitarget) 编译器，它通过使用可互换的后端处理器，为多种不同的计算机架构生成相应的可执行程序。
GCC 可被用作交互式编译器，可以使用 GCC 对所有设备与操作系统创建可执行程序，不需要局限于仅仅是运行 GCC 的平台。可以使用命令行选项来控制编译器在翻译源代码时应该遵循何种 C 标准。当使用命令行参数 -std=c99 启动 GCC 时，编译器支持 C99 标准。GCC 对 C11 标准的支持是不完整的，尤其是涉及定义在头文件 threads.h 中的多线程函数。GCC 的 C 链接库长期以来支持 POSIX 标准下与 C11 标准非常相似的多线程功能。
平台是指特定计算机芯片及其运行的操作系统的组合。
Alpha (Alpha AXP) is a 64-bit reduced instruction set computing (RISC) instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC), designed to replace their 32-bit VAX complex instruction set computer (CISC) ISA.
PA-RISC is an instruction set architecture (ISA) developed by Hewlett-Packard. As the name implies, it is a reduced instruction set computer (RISC) architecture, where the PA stands for Precision Architecture. The design is also referred to as HP/PA for Hewlett Packard Precision Architecture.

MinGW, a contraction of “Minimalist GNU for Windows”, is a minimalist development environment for native Microsoft Windows applications.
MinGW 是 Minimalist GNU for Windows 的缩写，是本机 Microsoft Windows 应用程序的极简主义开发环境。

MinGW compilers provide access to the functionality of the Microsoft C runtime and some language-specific runtimes. MinGW, being Minimalist, does not, and never will, attempt to provide a POSIX runtime environment for POSIX application deployment on MS-Windows.
MinGW 编译器提供对 Microsoft C 运行时功能和某些特定于语言的运行时的访问。MinGW 是 Minimalist，它不会，也绝不会尝试为 MS-Windows 上的 POSIX 应用程序部署提供 POSIX 运行时环境。
