Agreed. This does not improve compatibility; it breaks compatibility,
especially if they happen to #include any third-party library header
which is not _documented_ as being c89 compatible. (Even if it happens
to work with -std=c89 now, unless it's documented that it does and
always will, this might change in a future version.)

I had some potential ideas for other ways to do this. Anyway the
discussion is not entirely pointless since we need to address
"restrict" at some point too, and the mechanisms for doing so will be
similar (but worse, since "restrict" is not a keyword by default in
most compilers without -std=c99, unlike "inline" which works unless
you intentionally enable strict-mode)...
