The -mno-cygwin uses crtdll and not msvcrt but that might not matter.  You
could try it.  If that doesn't work for you try http://www.mingw.org and if
that doesn't work try http://pw32.sourceforge.net.

I just had a thought, since Nutcracker is a runtime it must come with headers
for that runtime.  Be sure you're using those headers and not the Cygwin
headers, you might want to use the -nostdinc switch in combination with the -I
switch.  Then when linking instead of using the gcc frontend use ld directly so
that you can specify yourself which runtime to use.  You can see what libraries
are added automagically by doing `gcc -v -o foo foo.c'.  You'll want to use all
but -lcygwin.

HTH,

Cheers,
