Hi all,

with r3264 and higher you can check the return code of mkgmap to
verify that all tiles were compiled. It will now return with a non-zero rc if
one of the typical problems like
"There is not enough room in a single garmin map ..."
occurs.

You may now also check the stdout for the lines
Number of MapFailedExceptions: 0
Number of ExitExceptions: 0
