Here are some that I #ifdefed on Linux just today:

timeval.  This is a tricky case, as there are actually 2 types on Darwin (timeval / timeval64), that map to 1 (as far as I know) on Linux.
timeval[64] members, which are in some platforms Int64, in some platforms __darwin_xx and in other platforms Int
POLLIN etc. is wrong IMO even on Darwin.  I opened SR-178 for this (and previously I filed a radar), but since that bug has sat for 2 months (and the radar for longer) without any comment it motivated me to investigate the DIY approach to these simple "importer bugs", as perhaps the core team is too busy.

Obviously I don't expect 100% portability (these are different OSes afterall), but there are several cases where the type differences feel more by accident than by design.

I will probably have a new list in a few days if interested, as I am still battling Linux-specific compile errors :-)
