Can I use GPL-covered editors such as GNU Emacs to develop nonfree programs? Can I use GPL-covered tools such as GCC to compile them? (#CanIUseGPLToolsForNF)
Yes, because the copyright on the editors and tools does not cover the code you write. Using them does not place any restrictions, legally, on the license you use for your code.
Some programs copy parts of themselves into the output for technical reasons—for example, Bison copies a standard parser program into its output file. In such cases, the copied text in the output is covered by the same license that covers it in the source code. Meanwhile, the part of the output which is derived from the program's input inherits the copyright status of the input.
As it happens, Bison can also be used to develop nonfree programs. This is because we decided to explicitly permit the use of the Bison standard parser program in Bison output files without restriction. We made the decision because there were other tools comparable to Bison which already permitted use for nonfree programs.

문제 없다고 하네요
감사합니다.
아 잘못 알고 있었네.. 흑
하지만 gcc 로 다른 프로그램을 만든거면 (다른 gpl 소스가 아닌) 전혀 상관없지요...
gcc 라는것은 그냥 툴일 뿐이니까요...
그럼 vim 으로 작성한 문서도 공개해야하는건 아니잖아요...
보통 gcc 자체는 문제가 되지 않습니다. 같이 엮여지는 라이브러리들이 문제지요

혹시 모르니까 칩 벤더쪽에도 확인 해 봐야겠네요
감사합니다.
