There is something funny with this option. The documentation says it is =
 =

"-fd" and also refer to it as "-fdl".

    -fd=3Dstring:

    This switch controls the Examiner=E2=80=99s treatment
    of FDL reserved words (see section 5.3). The
    option -fd=3Dreject, or any abbreviation of
    =E2=80=98reject=E2=80=99, rejects all FDL reserved words as being
    syntactically unacceptable. This is the default.
    The option -fd=3Daccept, or any abbreviation
    of =E2=80=98accept=E2=80=99, suppresses the rejection of FDL
    reserved words, but also prevents the
    generation of any proof files. Any string other
    than =E2=80=98reject=E2=80=99 or =E2=80=98accept=E2=80=99 (or their =
abbreviations)
    causes recognised FDL reserved words to be
    mangled on output by placing the string before
    the identifier, separated by a double underbar.
    As an example, -fdl=3Dpraxis would cause
    the identifier start to be output as
    praxis__start. Previously this was a binary
    option (-fdl_identifiers and -
    nofdl_identifiers) and this form is still
    supported, but deprecated.

Mangling is what is needed, indeed. If this work, I will use it as a  =

default option everywhere. Something like =E2=80=9C-fdl=3Darg=E2=80=9D o=
r =E2=80=9C-fdl=3Dapp=E2=80=9D should  =

be enough. Sources relying on this should add a note about in a README o=
r  =

some of the like.

There was an option which deals with only one specific keywords, and I  =

though this was the only one.

Thanks Rod, that's the tip of the day.

There is even better than a pragma Assert: a SPARK --# check.
