This doesn't seem to be the case with the current version of cppcheck. With:
cppcheck --force -q -Ilib/includes -Igl/ -Ilib/ -I. --error-exitcode=1 lib/ -i lib/unistring -i lib/minitasn1 -i lib/nettle/backport -i lib/nettle/ecc -j2 --enable=information --enable=warning --enable=style --enable=performance --enable=portability --std=c99 --suppressions-list=devel/cppcheck.suppressions --template='{id}:{file}:{line},{severity},{message}'
I got cppcheck.out.gz. I'll fix the typo anyway.
