I did some more searching on the cygwin list about the
stat() function. It is a feature of cygwin. If you
search on the cygwin ML you'll find plenty of
complaints when stat foo doesn't equal stat foo.exe.
This is a WAG because I haven't looked at the
subversion software. But because this is the UNIX
port of subversion, either APR or subversion itself is
using stat(). I wouldn't want to touch APR because I
don't know what other projects are using it and who
want the current behavior. My experiences on VIM
regarding mixing UNIX and Windows systems calls is a
complete hassle. I would just check to see if svn is
using stat() or the APR version of stat() and just do
it twice when required.
You should probably contact the cygwin subversion
maintainer because I think that they already have
cygwin specific patches they use.
(Shameless plug, if you check the VIM dev mailing list
you'll see a patch I submitted getting windows
clipboard functionality when compiling the non-gui
version on cygwin)
