FYI PortableXDR's output doesn't need these macros at all.
Sun's rpcgen was making some strange micro-optimization based (it
appears) on the size of the structure. If the size of the struct was
over some watermark, it would attempt to inline lots of code. You can
see what I mean by comparing the output of these two commands:
echo 'struct foo { int i0; int i1; int i2; };' | rpcgen -c -
echo 'struct foo { int i0; int i1; int i2; int i3; };' | rpcgen -c -
In PortableXDR I decided to leave inlining decisions to gcc.
