re PR c/28299 (ICE with -Wmissing-prototypes)
PR c/28299
* c-decl.c (start_function): Don't try to process prototype
information from old declaration that isn't a function.
testsuite:
* gcc.dg/funcdef-var-1.c, gcc.dg/funcdef-var-2.c: New tests.
* gcc.dg/pr20368-1.c, gcc.dg/pr20368-2.c, gcc.dg/pr20368-3.c:
Expect extra diagnostics.
