SYNOPSISmkc_check_decl <check_type> <what> [includes...]
mkc_check_decl-h
DESCRIPTION
check_type is either define, variable, func[0-9], type, member or
prototype. Depending on its value mkc_check_decl checks for define,
variable, function with specified number of arguments, type or a member
of structure in a specified header files includes by compiling a test
program. As a result it prints either 1 (success) or 0 (failure) to
stdout.
