           Summary: apr_shm_create incorrect comparison of
                    ERROR_ALREADY_EXISTS
           Product: APR
           Version: 1.2.8
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: major
          Priority: P2
         Component: APR
        AssignedTo: bugs@apr.apache.org
        ReportedBy: sobekjunk@gmail.com


Line 136 of shm.c has the following comparison:
    if (hMap && err == ERROR_ALREADY_EXISTS) {
        CloseHandle(hMap);
        return APR_EEXIST;
    }
Should be:
    if (hMap && APR_STATUS_IS_EEXIST(err)) {
        CloseHandle(hMap);
        return APR_EEXIST;
    }
Since apr_get_os_error() returns e + APR_OS_START_SYSERR the return of 
ERROR_ALREADY_EXISTS changes to, for windows, 720183 which does not equal 183L 
as defined in winerror.h.  The defined macro for IS_EEXIST compares the error 
against the correct values.  As the code is now, attempting to create shmem 
that already exists will return success.
