+Remove use of AM_C_PROTOTYPES to fix autoreconf
+
+The AM_C_PROTOTYPES macro no longer exists since automake 1.12. It
+existed to support de-ANSI-fication of code using ansi2knr. It was
+simply removed from coreutils m4/jm-macros.m4 in commit
+88873501cff9ed937edf969cedd693517ab0a293, but this change was not
+propagated to dc3dd, causing an autoreconf failure:
+
+configure.ac:45: error: automatic de-ANSI-fication support has been removed
+/home/peko/autobuild/instance-0/output/host/usr/share/aclocal-1.15/obsolete.m4:26: AM_C_PROTOTYPES is expanded from...
