RPC Problem with XDR |

| Issue |
A memory violation ocurrs for either xdr_getpos() or xdr_destroy(). Debugging this shows that in both cases the problem is the xdr_ops substructure which has some strange values. It seems that the xdrmem_create() did not correctly initialized the XDR structure.
This is using QNX 4.25, TCP/IP 4.25, and Watcom 10.6 with the latest updates.

| Solution |
All RPC programs need to be compiled using "-Wc,-ei". This means the compiler will allocate the smallest possible storage for an enumerated list, and can be used to force an integer to be allocated for all enumerated types.
This requirement is documented in 4.25.
