Yes - I tracked that down just now myself :]. Use
-Wl,--exclude-symbols=_cygwin_dll_entry@12
 on the .dll link line, and you will no longer need -lcygwin in the link
command.

Thats fixed the segfaulting for me, and I'm back to libtool. I suspect
that there are a number of symbols that will need to be excluded from
automatic exporting, and I'll generate a patch to ld that will include
Pauls' patch, and exclude those extra symbols.

Thanks for the help,

Rob
