In fact I can build git with this command:

make CFLAGS="-std=c89 -pedantic -Dinline=__inline -D_GNU_SOURCE"

if I fix all C++ comments. It warns a lot about "flexible array members" and other violations, but the resulting executable passes the test. That's Fedora Core 5 with gcc 4.1.1.

What I meant it that if we go all the way to strict c89 (even with a modern libc) and fix all the warnings, it will be much more than what is needed to support Sun's C compiler with its partial c99 support.

We can satisfy the Sun's compiler and yet retain flexible arrays and other c99 goodies.

Maybe I'm missing your point (or you joke).
