I haven't really understood what happens when a dll is built with cygwin. dlltool generates the .def file and the exports.o used in the next gcc step. See http://www.gnu.org/software/binutils/manual/html_chapter/binutils_13.html http://www.cygwin.com/cygwin-ug-net/dll.html
I was able to get a libmemutil.dll without errors by: gcc -mno-cygwin -mwindows -std=c99 -c libmemutil.c dlltool -z libmeutil.def --export-all-symbols -e exports.o -l libmemutil.lib libmemutil.o gcc -shared -mno-cygwin -mwindows libmemutil.o exports.o -o libmemutil.dll A while ago, when I made the dlls for elephant 0.6.0, my first try was MSVC, guided by http://bc.tech.coop/blog/041007.html However, the available free MSVC appeared to have no preset dll-project any more. I had to try compiler switches ... and found cygwin easier. This should mean that not every lisp-on-windows-user has MSVC installed (and is able to use it. cygwin is easy to install).
