- The SunPro C 3.0 compiler, under strict checking options, emits the
- following warnings:
-

- "tif_open.c", line 45: warning: constant promoted to unsigned long
- "tif_open.c", line 45: warning: initializer does not fit: 0xffffffff
-
- The warnings are generated to indicate that an unsigned value with
- the high bit set cannot be truly represented as a signed value.
- These messages may be eliminated by converting the tif_typemask member
- of a struct tiff to an unsigned value as it is actually used, with the
- changes noted below to the tiffiop.h and tif_open.c files.
