The POSIX standard *requires* that the ?STx?DT format precludes
the use of zone files.

Any OS which uses the zoneinfo files is not compliant when the $TZ
variable can be parsed under the POSIX rules.

Okay, well the NIH zdump (and, as it happens, the Sol 10 zdump.c I got to 
compile on Sol 2.7), "trussed" shows:
open("/usr/share/lib/zoneinfo/GMT", O_RDONLY)   = 3
open("/usr/share/lib/zoneinfo/CST6CDT", O_RDONLY) = 3

So I guess the reason it 'works' is its not properly POSIX ... so the 
question (to my mind) remains - where does Sol's POSIX-valid zdump get its 
TZ info?  From a library file?  That would be the one we need to update.
