It looks like Solaris doesn't mind EOF during argument collection, but does 
mind EOF during strings:

$ echo "define(a,\`1" > a.m4   
$ echo "2')a" > b.m4
$ m4 a.m4 b.m4
NONE:0: m4: ERROR: EOF in string
$ /usr/ccs/bin/m4 a.m4 b.m4

/usr/ccs/bin/m4:a.m4:2 EOF in quote

But if we are going to allow partial input, I would argue that partial strings 
should not behave any differently than partial arguments when we are not in
-G/--traditional mode.
