Forgot to mention that this is a good thing:
We add macros there (they are now almost complete) to
facilitate the programming of the parser interface. Eg.:

    input = G_define_option();
    input->key             = "input";
    input->type            = TYPE_STRING;
    input->required        = YES;
    input->multiple        = NO;
    input->gisprompt       = "old,dig,vector";
    input->description     = "vector input file";

was simplified to

    input  = G_define_standard_option(G_OPT_V_INPUT);

(as defined in lib/gis/parser.c).

Additional positive side effects:
- standardized wording
- messages translated to other languages in one place only

Only, which each change in lib/gis/parser.c, a full recompilation
after "make distclean" is needed to avoid shifted parameters
as you have seen.

Hope this clarifies it.
