Comment (by simonmar):
Replying to [comment:3 ksf]:
> Solution 2 to issue 2 (running hsc2hs with the target's headers on the
host) needs a cross-compiler, at least if the system's bytesizes differ.
Otherwise, offsetof is going to return borkage, even if given the right
headers.
In the past we've avoided using `hsc2hs` in parts of the libraries that
are required by the bootstrap for exactly this reason. I think we
recently regressed in this area since I started using `System.Posix` stuff
to implement `System.Directory`; my humble apologies. It was fragile to
start with though.
We either have to come up with a solution for using hsc2hs (take the
intermediate C files to the target and compile/run them?) or convert .hsc
files to autoconf + CPP (yeuch).
