; Test case 4 - Missing nested enumerations.

; The above test is used to illustrate a scope issue found in the Clang

; In the following logical views, we can see that the DWARF debug
; information generated by the Clang compiler does not include any
; references to the enumerators 'RED' and 'BLUE'. The DWARF generated
; by GCC, does include such references.
