Hello Frank,

Thanks for the info.  So far I've been using the fwtools.  Now, I tried 
building gdal for the first time but I got the following error message at 
the end of the process

C:\Arquivos de programas\Microsoft Visual Studio\VC98\lib\MSVCRT.lib : 
fatal error LNK1106: invalid file or disk full: cannot seek to 
0x35894cc8NMAKE : fatal error U1077: 'link' : return code '0xc'
Stop.

The HD am building on has 42 GB of free space.  Any suggestions on what's 
going on?

Thanks in advance.

Reinaldo
