Curt, 

I have committed fixes for the item you listed (in libtiff, libgeotiff,
proj and GDAL) but my attempts to reproduce the warning report
with -Wstrict-prototypes failed.  I don't want -Wno-unused-parameter
since it generates alot of junk warnings in functions that legimately
don't need to use all their arguments.  Likewise, I don't want
warnings on pointer arthmetic since I do that frequently and
legimately.

Best regards,
