Там упоминалость чтот-то о GNU c++. Во что написано на ихнем сайте The most popular of all C++ environments is Microsoft's Visual C++, but the software is expensive. Fortunately, there are public domain C++ environments ? the most popular of which is GNU C++. (Pronounce GNU like this: guh NEW). You can download public domain programs from the Internet. Some of these programs are not free ? you are either encouraged to or required to pay some usually small fee. You do not have to pay to use GNU C++.
GNU stands for the circular definition "GNU is Not UNIX." This joke goes way back to the early days of C++ ? just accept it as is. GNU is a series of tools built by the Free Software Foundation.
GNU C++ is not some bug-ridden, limited edition C++ compiler from some fly-by-night group of developers. GNU C++ is a full-fledged C++ environment. GNU C++ supports the entire C++ language and executes all C++ programs.
GNU C++ is not a Windows development package for the Windows environment. You'll have to break open the wallet and go for a commercial package like Visual C++.
