int21 creat flags

[Ferenc Wagner]

               Hello,

Is there any reason why Wine's implementation of DOS
function 0x3c (create file with handle) explicitly ignores
the invalid flag bits (volume label and directory)?  NT4
returns error if any of these bits is set.  Some PKSFX files
have problem with this, since they try to create directories
the invalid way (function 0x3c, flag=0x30, that is, archive
directory), and they create FILES instead, which they can
not cd later, of course...  I was not able to find any
information on possible extended use of the above function.
So again, is there any reason why Wine does not conform the
specification?
