[gs-devel] Windows 95 and Visual Studio 2005

[Ray Johnston]

Hi Russell,

Unless the 2003 code runs measurably slower, using 2003 for release
builds seems reasonable.

Also we should add a note to the documentation about the problem with
2005 builds running on Win95.

Do you know if a build with 2003 is any slower?

I assume that since you didn't mention it, that Win98 and Me are OK.

Regards,
Ray
