This is a reduced version of an originally much larger patch.
We will keep the definition of the ulint, lint data types unchanged,
and we will not be replacing fprintf() calls with ib_logf().

On Windows, use the standard format strings instead of nonstandard
extensions.

This patch fixes some errors in format strings.
Most notably, an IMPORT TABLESPACE error message in InnoDB was
displaying the number of columns instead of the mismatching flags.
