No, I was using the MSYS environment. However, the Parrot codebase makes 
use of some headers (in particular tchar.h and direct.h), which aren't 
part of the msys-w32api package.

I didn't want to make changes to the Parrot code yet, just trying to get 
it to build and thus added the MinGW include directory to the search 
path (after the MSYS directory, of course).

This, however, messed up the startup code, probably by pulling in _mingw.h.

I've made appropriate changes to the Parrot codebase and actually got it 
to compile. What still needs to be done is adding code for path 
translations to the Win32 platform files, but I don't expect any major 
problems - in fact, I'm mostly there already, just blocking on some 
spare time...

Btw, MSYS makes use of the deprecated cygwin_conv_to_win32_path(), which 
doesn't know how to deal with unicode, instead of the more recent 
cygwin_conv_path().

Are there plans to update MSYS to a more recent version of Cygwin?

As a workaround, I'm converting the paths to UTF-8 and just use the 
legacy function - don't know if it actually works yet, but I don't see a 
reason why it shouldn't...
