Huge chunks of this code have been rewritten on trunk. (E.g. the dirent code
and some parts of io.c). Can you update this patch to work against trunk?
The path changes look ok. Your changes in io.c use '//'-style comments and
most likely break on other operating systems.
E.g.

> ignore the error. */

Changes the check from
#define APR_STATUS_IS_EINVAL(s) ((s) == APR_EINVAL \
|| (s) == APR_OS_START_SYSERR + ERROR_INVALID_ACCESS \
|| (s) == APR_OS_START_SYSERR + ERROR_INVALID_DATA \
|| (s) == APR_OS_START_SYSERR + ERROR_INVALID_FUNCTION \
|| (s) == APR_OS_START_SYSERR + ERROR_INVALID_HANDLE \
|| (s) == APR_OS_START_SYSERR + ERROR_INVALID_PARAMETER \
|| (s) == APR_OS_START_SYSERR + ERROR_NEGATIVE_SEEK)
To just checking for APR_EINVAL on Windows.
We don't keep the old code as comments in our code; we use a version control
system to look at the old code ;-)

This will return error code -1 (Undefined behavior), where it used to give
the os error.
(Similar cases in a few places)
