Compiling for Shared Libraries

I see. That explains it. Thank you.

I will try that. My existing 64-bit binary distribution appears to be 
position-independent.

Trevor B:

Very good. Thank you.

Yes, 2.4.1, and I had no difficulties. But following your link to the 
patch, I see that the error I would have obtained would be:

gcc: c-parse.c: No such file or directory
gcc: no input files

And this is exactly the error that thwarted me six months ago, when I 
tried to compile on 64-bit Linux. So it appears that Bison has been 
fixed, and I now understand what has been going wrong, because a 
colleague was able to compile on another, older 64-bit machine. So thank 
you for that also.

Your, Kevan
