re PR c/3116 (Bug with using oldstyle prototype declarations)
* c-decl.c (store_parm_decls): When comparing types in an
old-style function declaration with those from a previous
prototype, compare the unqualified versions of parameter types.
Fixes PR c/3116.
testsuite:
* gcc.c-torture/compile/20010611-1.c: New test.
