But not clang or LLVM. I think this conflicts with your previous statement that using Clang for some features would be fine as long as Emacs supports using GCC for the same features. Thanks for calling my attention to this wrinkle of the issue. Features that only want to do C (or C++) compilation may as well be implemented to work with any and all compilers. For features that interact with the compiler beyond just using it to compile a program, and therefore can't easily be implemented to work with any and all compilers, there are two sensible approaches: * Support only GCC. * Support GCC first; once GCC is supported, support for other compilers is acceptable too. Rather than making a general decision a priori, I'd rather look at these cases individually when they arise. After deciding a few such cases, I hope I will see a pattern that would suggest a general policy. -- Dr Richard Stallman President, Free Software Foundation 51 Franklin St Boston MA 02110 USA www.fsf.org www.gnu.org Skype: No way!
