While it's easy to work around these simply by changing some defines in
port/cpl_config.h, I now run into trouble while compiling the included
TIFF library (with beta2 as well as RC1). I'm pretty much surprised
because I thought the TIFF library should be expected to be "portable
by design" (....  or by history  ;-)

Am I being blocked by incorrect compiler behaviour ?
