FYI: fix simple C++ link code m4 quoting (was: FYI: ksh bug on Tru64 UNIX causes current libtool failure)

Hi Nicolas,

Your last mail requires several (>=3) distinct answers.
First, easiest, and most embarrassing:

I have applied the following fix to CVS branch-1-5 and HEAD.
Can't believe how much sh*t you can throw at compilers and have them
accept it, too...

(And I just noted another bug in branch-1-5, sheesh..)

Cheers,
Ralf
