HUGSROOT in version.c

[Neil Mitchell]

Hi,

In version.c, HUGSROOT is defined as:

#define HUGSROOT ("SOFTWARE\\Haskell\\Hugs\\Winhugs" VERSION_STRING "\\")

This means that the settings from one installation of Hugs do not
persist when the user installs a new version. This is unfortunate as
it means that when people upgrade, they will loose all their
preferences such as text editor, along with their hugs options as
well.

Is there a good reason for this behaviour? Are options between
different versions really totally incompatible?

Thanks

Neil
