I posted a message on the libraries list a couple of days ago about a compile problem I'm having. I haven't got any nibbles. Because I now suspect this is a GHC problem, I'm posting here to see it I can get this resolved. Rather than repost the details, allow me to refer you to (http://permalink.gmane.org/gmane.comp.lang.haskell.libraries/ 4873) which contains a complete description of the problem. As far as I can tell, the GHC install is missing a necessary system header, or it isn't being found, or somesuch. I tried crawling through the headers to find out what the problem is, but, as per usual, the system headers are almost totally incomprehensible. I've tried using both Cygwin and MSYS shells, but the results are identical. As I said in the above message, I'm not very familiar with this environment, so I'd appreciate pointers in the correct direction if I've made some mistake.
