It is wise to assure that the test suite passes on both big and little endian machines before preparing any release.

FWIW, HEAD does pass as of yesterday on my old G4 Mac (32-bit bigendian).

Today I just get a core dump with 32-bit x86:

Core was generated by `/home/bfriesen/build/tiff-head-32bit/test/.libs/raw_decode'.

Program terminated with signal 11, Segmentation fault.

I did add a change so that the test can be run with builddir != srcdir

but this core dump seems unlikely to be due to those changes.
