> On the MinGW platform, files can only be read-write or read-only. It lacks concepts like the executable-bit, user-id, group-id and the distinction between "user", "group" and "other" permissions flags.

> The solution was to define the missing flags as zero, and comment out the code which depend on the availability of chown.

> In my opinion, the resulting behavior is correct from the point of view of a Windows user, in the sense that the backup files are still being marked as read-only.

I think we ought to compare notes on the fixes needed for MinGW, no
point in duplicating work. (OTOH, many of my "fixes" were quick hacks to
make it compile).

My (hacks) are at http://www2.eng.cam.ac.uk/~pcjc2/geda/fix_win32.diff

Many of the fixes probably ought to be "feature" based #ifdef rather
than #ifdef WIN32, but they give the general impression of what needs
doing to make a working gschem.

There may even be some bits which ought to get included in mainstream
geda, such as the wrong guile header file which is used in at least one
place.

Regards,

Peter
