msys-1.18 with basic unicode support

Using kbless patchset from msysgit and a whole slew of work i managed to 
make a version that supports multibyte
and a basic set of unicode functions.

It took quite some work because he was missing a few exports in 
cygwin.din and the wrappers for the w32api unicode functions where 
impossible to compile.

I also added strtoll and strtoull besides stdint and inttypes to the build.

i have tested it against bash zsh and libiconv and they all work and 
report both multibyte an unicode functionality.

I can upload a patch or the modified code for you to try out.
