Hello,
The following is a patch for the PR92209,which gives a warning when
the function prototype does not specify its argument type.In this
patch there has been a change in the warning message displayed for
-Wstrict-prototypes to specify its argument types.I have also added
the testcase for it.
Regtested on x86_64,OK for commit? Please do review it.
