Re: Error compiling the C-interface runtime on x86-linux

The old C interface code that ou are trying to build hasn't been  
actively maintained.
We would recommend using the newer nlffigen tool for C interfaces.   
The file

	src/ml-nlffigen/README

has some documentation about how to use the tool.  The one thing that  
the old mechanism
supported, which is not yet supported by the new tool, is callbacks.

Hope this helps.
