-O2 -Wall -Wextra -Wshadow -pedantic --std=c99

and the --std=c99 part explicitly allows declarations after statements.
I don't know what to suggest if a compiler doesn't follow an ISO standard
16 years after it's published.

Sometimes I'll also add
-Wsign-compare -Wundef -Wredundant-decls -Wpointer-arith -Wcast-qual -Wcast-align -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Winline
The amazing thing is that clang folks will accept all of those options, too,
so they can no longer be labeled purely gcc-specific.
