I wonder if the Windows or Solaris compilers work. Anyway, I'm fine with this. I tend to doubt anybody uses anything else, on the theory that if they did, we'd probably have seen patches to work around problems. I suppose we can revert this or just ask people to write wrapper scripts for any compiler not supporting this feature. The depcomp stuff was more important for C and the olden times when other compilers were in use. Approved-By: Tom Tromey Tom
