As a quick workaround, consider putting this in a .gitattributes file:

*.c	diff=cpp

This will tell git diff to use the predefined regex for finding function
headers in c++ files for all C files as well. It differs from the
default C regex in that it tries to exclude visibility class labels
("protected:" etc) and therefore incidentally excludes all labels ;-)

Enjoy!
