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.
