[gdal-dev] Make stdin in OGR/GDAL tools cross-platform?

[Even Rouault]

Stefan,

/dev/stdin is indeed Unix specific, but /vsistdin/ is a special filename within
GDAL virtual file system handling. So I believe /vsistdin/ should also work on
Windows, but I'm not sure this has been very much tested. Just try !
