[Gdal-dev] VSIFSeekL() - making vsi_l_offset signed instead of unsigned

[Frank Warmerdam]

Folks,

I have discovered that the vsi_l_offset type used for offsets arguments
to VSIFSeekL() are GUIntBig - an unsigned type, instead of a signed type
like size_t of the fseek() POSIX analog.

I would like to change vsi_l_offset in 1.5 to be of type GIntBig instead
so that constructions like:

     	if( VSIFSeekL( poGDS->fp, -1, SEEK_CUR ) != 0 )

will work properly.  I have prepared a ticket on the issue, and I'm wondering
if there are any objections to my doing so.

Best regards,
