I saw a funny thing on my way through apr_errno.h:

/**
 * @see APR_STATUS_IS_EAGAIN
 * @warning use APR_STATUS_IS_EAGAIN instead of just testing this value
 */
#ifdef EAGAIN
#define APR_EAGAIN EAGAIN
#elif defined(EWOULDBLOCK)
#define APR_EAGAIN EWOULDBLOCK
#else
#define APR_EAGAIN (APR_OS_START_CANONERR + 13)
#endif

And lots of other similar defines. Which means that some APR codes may
well be different on different systems, doesn't it?
