-Wall is a GCC option made for front ends to languages
other than Ada, in GCC.

Use -gnatwa instead.

Guessing, though, there are occurrences of F and C in
what GNAT generates as sources from the internal tree,
with -gnatdg.

F and C are out mode parameters that seem to be related to
primitive operations.  As said, just a wild guess.
