I've just encountered a problem with pvm_psend and pvm_precv -- they
don't appear to be reliable across heterogeneous architectures if
anything other than PVM_BYTE is specified. 

Looking at lpvm.c it appears that the XDR scheme is bypassed
completely by working out the length of the data in bytes according to
the data sizes on the sending and receiving machines independently. Is
there a patch for this, or is it a feature?
