zh.po causes error on Solaris 9, gcc 3.1.1

[David Meissner]

Compilation of sh-utils-2.0 failed on Solaris 9, running gcc 3.1.1, with the
following error:

make[2]: Entering directory `/export/home/dmeissne/sh-utils-2.0/po'
/usr/bin/msgfmt -o zh.mo zh.po
ERROR: Line 804 (zh.po): Invalid character found.
make[2]: *** [zh.mo] Error 2
make[2]: Leaving directory `/export/home/dmeissne/sh-utils-2.0/po'

I removed references to zh.* from the Makefile in the po directory and
compilation completed with no errors.
