PARSE.MISSING.DS : Missing Declaration Specifiers

Summary

A declaration is required to have both a type specifier and a storage class specifier, but has neither.

This includes the following situations.

If one of these declarations is present but your compiler does not require a type specifier, a Nonstandard Implicit Integer warning is issued instead.

See also: Missing Type Specifier

This warning class is derived from a C/C++ parser warning.

Enabling Checks for this warning class are enabled by default. However, warning instances of this class that are issued as parser errors (rather than parser warnings) will be discarded when using factory configuration settings. To prevent these instances from being discarded, add the following WARNING_FILTER rule to the project configuration file. 
WARNING_FILTER += allow class="Missing Declaration Specifiers"
To disable checks for this warning class, add the following WARNING_FILTER rule to the project configuration file. 
WARNING_FILTER += discard class="Missing Declaration Specifiers"
