I assume you mean aips not aips++

The answer is no - I do not have wisdom.  I worry that it may not work
however.  Our method of doing dynamic memory has been sabotaged by
some implementations of memory management in 64-bit machines.  Our
dynamic memory requires that we can use a 32-bit integer subscript wrt
to an address in the program to get to the dynamic memory region.  I
worked with a machine in Italy that gave dynamic memory from the top
of the 64-bit address space while putting the programs at the bottom.

The compiles work fine but be sure to run Y2K and DDT.
