#### Test the selection of the macro scope by the current frame.
### A table of functions, in the order they will be reached, which is
### also the order they appear in the preprocessed output. Each entry
### has the form {FUNCNAME WHERE KFAILWHERE}, where:
### - FUNCNAME is the name of the function,
### - WHERE is the definition we expect to see for the macro `WHERE', as
### returned by `info_macro', and
### - KFAILWHERE is an alternate definition which should be reported
### as a `known failure', due to GDB's inability to distinguish multiple
### #inclusions of the same file.
### KFAILWHERE may be omitted.
