-Wdeclaration-after-statement should do for gcc (untested though).
I gave that a quick try. It's not catching declarations in the for
statements in either gcc or clang.
The best compromise I can come up with is to target std=gnu90 and enable
pedantic warnings. In addition to the things indicated by the patch, we
would not be able to have trailing commas in enum declarations.
I'll work on this tonight.
