Modifying Eric's procedure to work with 'gcc version 2.95.3-5 (cygwin
special)' resulted in the following steps (well, it works for the example
at least):

(3) There is no step (3)!

>(4) Change the 'loadlib' line in loadlib\test.lua to:

assert(loadlib(D.."/mylib.dll","mylib_start"))

>(5) Build everything:

gcc -mno-cygwin -shared -o lua.dll -I./include src/*.c \
src/lib/*.c loadlib/etc/windows.c

gcc -mno-cygwin -o lua.exe -I./include -L. -llua src/lua/*.c

gcc -mno-cygwin -shared -o mylib.dll -I./include -L. -llua \
loadlib/mylib.c

(6) Run it from Windows command prompt (no cygwin1.dll in PATH!):

  C:\lua-4.1-work4dll\lua.exe loadlib\test.lua
  Hello from mylib
