Of course.  But he wrote that he was "still interested (to some
degree) in pre-ANSI compilers".  I took this to have its usual
meaning.

That is, I assume he's mildly interested in pre-ANSI compilers that
shipped some time in the last decade or so; that he's not at all
interested in the original Unix Version 7 C compiler, which is long
dead; and that his interest level in other nonstandard compilers
primarily depends on how likely someone will actually want to use
those compilers to build the next version of GNU "make".

In that light I don't think my comments were misleading. However, if
you know of any C compilers that are plausible targets for the next
version of GNU make, and which don't support #elif and/or require "#"
to be in column 1, I'd like to hear about them.
