The current display of parameters for tiffcp is hardcoded in tiffcp.c. Even when certain compression libraries are not built, tiffcp will display all the options, including the non-functioning ones, which to me seems very inelegant.

Agreed.

I propose making the display conditional upon the real support for those options. Something like the following (starting at line 473 of tiffcp.c):

It would be better to use the TIFFIsCODECConfigured() function to test if a codec is supported rather than using something hard-coded since the tiff library may be updated without updating the utility.

I don't quite know what to make of the "-c sgilog" option, though. Is it an inbuilt function?

Yes.
