I have noticed an incompatibility between the version of OS/2 V1.20 that
I received from Microsoft with the SDK and the version that my customers
have received from IBM.  

The affected call is DosQCurDir.  The third argument is a pointer to
a variable that has the size of the buffer.  It is documented as a 
PUSHORT.  I had set the value of this variable equal to 0xffff to
effectively disable the length check.  This worked in the Microsoft
version.  It did not in the IBM version.  If I set the variable to
0x7fff it worked in the IBM version, leading me to believe that IBM
treats the parameter as a PSHORT instead of a PUSHORT.
