[wdiff-bugs] wdiff 0.5.91 distclean, warnings

[Karl Berry]

Sorry if these have already been reported.

Two trivial warnings and possibly non-trivial warning during the compile
(no special options to configure, gcc 4.2.1, GNU/Linux):
wdiff.c:1161: warning: return type of 'main' is not 'int'
wdiff.c:600: warning: the use of `tmpnam' is dangerous, better use `mkstemp'
wdiff2.c:230: warning: return type of 'main' is not 'int'

And make distclean fails:
make[1]: Entering directory `/usr/local/gnu/src/wdiff-0.5.91'
make[1]: *** No rule to make target `clean-local-legacy', needed by 
`clean-local'.  Stop.

Best,
Karl
