I have already written for g51 new
Option * G_define_standard_option (int opt)
where opt may be 
#define G_OPT_WHERE      0 /* SQL where conditions */
#define G_OPT_R_INPUT  100 /* old input raster */
#define G_OPT_R_OUTPUT 101 /* new output raster */
#define G_OPT_R_MAP    102 /* old input raster */
#define G_OPT_V_INPUT  200 /* old input vector */
#define G_OPT_V_OUTPUT 201 /* new output vector */
#define G_OPT_V_MAP    202 /* old input vector */
#define G_OPT_V_TYPE   203 /* primitive type */
#define G_OPT_V_FIELD  204 /* field number */
#define G_OPT_V_CAT    205 /* one category */
#define G_OPT_V_CATS   206 /* more categories */
....

and I started to upgrade modules for this on Tuesday. 
Now, I don't know if i should commit or remove that again
and wait for some more radical changes in parser?
