NAME 
t/codingstd/c_arg_assert.t - checks that all the headerizer asserts are used
SYNOPSIS
# test all files
% prove t/codingstd/c_arg_assert.t
DESCRIPTION
Finds all the argument guards generated by headerizer (asserts to enforce the non-NULLness of specially marked pointers) are actually used. Verifies that macros are invoked on a sane position.
