+Errors are diagnostic messages that report that the GNU Fortran compiler
+cannot compile the relevant piece of source code. The compiler will
+continue to process the program in an attempt to report further errors
+to aid in debugging, but will not produce any compiled output.
+
Warnings are diagnostic messages that report constructions which
-are not inherently erroneous but which are risky or suggest there
-might have been an error.
+are not inherently erroneous but which are risky or suggest there is
+likely to be a bug in the program. Unless @option{-Werrors} is specified,
+they do not prevent compilation of the program.
You can request many specific warnings with options beginning @option{-W},
for example @option{-Wimplicit} to request warnings on implicit
for example, @option{-Wno-implicit}. This manual lists only one of the
two forms, whichever is not the default.
-These options control the amount and kinds of warnings produced by GNU

+GNU Fortran bails out rather than attempting to continue processing the

Some of these have no effect when compiling programs written in Fortran.
