When I looked at it, I had the feeling that the easiest way would be to 
add a flag which, if set, leaves out the map creation part. This would 
mean (in in.c)

- conditionalising lines 214-215 and all calls to Vect_delete and 
Vect_map_add_dblink and other functions using &Map as parameter on the 
flag not being set
- not use Vect_default_field_info and Fi (lines 300ff), but directly use 
db_get_connection() and a table_name parameter given by the user (with 
default being the same name as the file ?).

It should use the current db.connect settings (that's what 
db_get_connection() should give you), and so create any kind of table 
(dbf or others).
