Sure, I can do that, but shouldn't this convention be documented in
SubmittingPatches?

Again, I can do that no problem, but again this convention is
undocumented and I am not psychic ;-)  I see that a patch was provided
5 years ago to document this, but was apparently never pulled in:

    http://thread.gmane.org/gmane.comp.version-control.git/47843/focus=48015

It would save everybody's time if these things are documented, since
then they wouldn't create noise during the review process.

I also see in the same thread that a patch to add
-Wdeclaration-after-statement to CFLAGS was also offered but never
pulled in, presumably on the stated grounds that that option was
relatively recent 5 years ago.  But wouldn't it be trivial to do

    gcc -v --help 2>&1 | grep declaration-after-statement

at build-time?

I'm also curious to know why this convention exists.  Are people
really still compiling git with compilers which don't support C99?

Thanks, I'll take a look at these suggestions tomorrow.
