Hi Even,

Since you ask, I can tell you that changing "/MD" to "/MDd" is one of just
two remaining edits that I have to make to nmake.opt before I build a new
version of GDAL.



Yup, me too and I think most GDAL as library users on Windows do it as
well.



(By the way, the other item in nmake.opt that I can't override with an
EXT_NMAKE_OPT
file is that we don't want to build with

ODBC_SUPPORTED = 1

If that were changed to use the !IFNDEF ODBC_SUPPORTED then I wouldn't have
to edit nmake.opt at all which would be very handy.)



Then, why not submit a patch or pull request. I think it's good idea.
