The call was (from the top-level of the FreeType tree):
cppcheck --force \
--enable=all \
-I /usr/include \
-I /usr/local/include \
-I /usr/lib/gcc/i586-suse-linux/4.7/include \
-I include \
-I include/freetype \
-I include/freetype/config \
-I include/freetype/internal \
-DFT2_BUILD_LIBRARY \
. &> cppcheck.log
using cppcheck git commit f7e93f99.
Note that cppcheck still can't handle `#include FOO' (with `FOO' a
macro).
