[winGRASS] GRASS6beta1 on WINDOWS/MINGW / raster read error

[Javier A. Yebrin]

Thanks a lot Glynn. 

Thanks to you and Luke from the MINGW-users list I've manage to fix this.

 http://www.mingw.org/MinGWiki/index.php/binary

For the moment I'm using the 4th method listed in the previous formentioned
site:

[...]
4) Yet again another way:

#include <stdlib.h> /* _fmode */
#include <fcntl.h> /*  _O_BINARY */

unsigned int _CRT_fmode = _O_BINARY;

main ()
{
}
[...]

Cheers

Javier
