[Mono-devel-list] Patch for monodis AIX symbol clash

[Bernie Solomon]

Thanks for the hints, I'd assumed the calling convention was similar
to one of the existing platforms.

I'd got as far as realizing the function descriptors were needed (at
least in the interpreter which I was looking at first as I am more
familiar with this code) and found the magic _ptrgl helper
function that is used by default by the IBM compiler to call
a function pointer. Will either need to use it or inline the equivalent.

There are also just plain porting issues re semaphores, AIO and
so on....

Low priority for me but we will see what progress can be made
but I know others are interested in this as well.
