[Tinyos-help] Can't Blink with "make micaz sim"

[Carlos Perez]

I believe I was able to fix the library issue. But now I'm getting this
error:

  linking into shared object ./_TOSSIM.dll
g++ -fpic -W1,--enabled-auto-image-base   build/micaz/pytossim.o
build/micaz/sim.o build/micaz/tossim.o -L/python2.4 -lstdc++ -lpython2.4 -o
_TOSSIM.dll
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../libcygwin.a(libcmain.o)::
undefined reference to `_WinMain at 16'

I googled the error for some solutions, and tried adding "-Wl,u,_WinMain at 16"
to the linking command but that didn't help. Any ideas on this one?
