It is known that it is not possible to create a gmapsupp with an
address index by combining gmapsupp.img files.

I did not know that attempts to combine gmapsupp.img files that contain
an index will give you an empty file. This bug has actually been there
since r1334, but didn't show up since our gmapsupp files did not contain 
an index.

Since you cannot create an index while combining gmapsupp files, then a
workaround is to avoid creating the index in the individual files.

The attached patch solves the problem with combining in any case.

Thanks,

..Steve
