[Haskell-cafe] c2hs, size_t, and CSize -- argh!

I'm running into a problem with c2hs and how it parses the C typedef
'size_t'. On 32bit systems, this ends up being parsed as a CUInt. On 64bit
systems, this ends up as a CULong. This gets especially sticky with function
In order to make bindings with c2hs that work across the different word
sizes, I have to write an indirection layer in C that defines wrappers for
functions or re-defines typedef's for function pointers to include 'unsigned
long' instead of 'size_t'.
I see there is a ticket open for this:
Has any one else run into this issue? Is there a good workaround that
doesn't involve writing a C function/typedef for each collision?
