Simon,

It has been my policy to only commit nmake.opt files when strictly
necessary, and rather than committing my "working" version, I generally
get a clean copy from CVS, make my additions, and commit that reducing
merge/conflict issues.  Problems will sometimes still occur.

My issue with this is aI don't want to add a manual step for users starting
new with GDAL. I link that the "nmake /f makefile.vc" command will generally
work out of the box for basic builds of GDAL on windows.   If it were
possible to have a makefile (for NMAKE) which could copy a template
nmake.opt.in to nmake.opt if nmake.opt didn't exist, before including it, then
I would be glad to make the change but I don't know of any way to accomplish
this.

In short, for now I would just ask that people be careful committing changes
to nmake.opt to change the bare minimum.

Best regards,
