Typical Error Situations

        idnetifier: $[a-zA-Z][A-Za-z_0-9]* [mkidn]
    ==> No GLA specification for identifier

  • errors in complex regular expressions, especially with white space and quoting special characters 

    C_FLOAT    $((([0-9]+\.[0-9]*|\.[0-9]+)((e|E)(\+|-)?[0-9]+)?)|
           ([0-9]+(e|E)(\+|-)?[0-9]+))[fFlL]? [mkstr]
