First of all, I think it's a good idea. But you would need at least
two functions as implemented inside of Cygwin:
cygwin_conv_to_win32_path(IN const char *posix_path, OUT char *win32_path);
cygwin_conv_to_posix_path(IN const char *win32_path, OUT char *posix_path);
or use a C++ class as the `path_conv' class in Cygwin.
Unfortunately it's not there in a form which allows using it standalone.
So, if you're volunteering to write such a function you would have to
look through the cygwin sources and then rewrite them appropriately.
The important stuff for the path conversion is in path.cc.
BTW, "it would be nice"(tm) if such a functionality is compilable
using MingW and VC to give the vendor of the tools a choice. Oh,
and, "it would be nicer"(tm) if the code also recognizes Cygwin
symlinks, both, old and new form...
Looking forward,
Corinna
