Re: [PATCH] On Cygwin support both UNIX and DOS style path-names

In fact Cygwin supports both, so make Git agree with this.

Why not indeed, especially since both are already supported under MinGW.

+#define has_dos_drive_prefix(path) (isalpha(*(path)) && (path)[1] == ':')
+#define is_dir_sep(c) ((c) == '/' || (c) == '\\')

I think that by defining is_dir_sep you enable DOS/Windows style paths
throughout Git, so you might want to check compat/mingw.h for other, related
changes. You will probably at least want the MinGW version of
find_last_dir_sep as well, because the default find_last_dir_sep doesn't use
is_dir_sep.
