[Wien] Again "Invalid null command"

No, all four  \<newline> should be removed:
if !($?cmplx) then
set cmplx=`cut  .....   ;END{print c}'`
endif
So, I think this is not the awk's fault, though they are different in two cases.
Good:  awk --version      GNU Awk 3.1.4
Bad:  awk -W version     mawk 1.3.3 Nov 1996

In my old version command "csh" calls "tcsh". 
In bad case command "csh" calls some "bsd-csh" and I cannot obtain version. 
If I force to call tcsh instead of this "bsd-csh" then it correctly determines the complex case. So, it is enough to make a redirection of csh to tcsh. I'll ask our administrator why this exotic version appeared.
man csh (good) gives:
"a newline  preceded  by a '\' is equivalent to a blank, but inside quotes this sequence results in a newline."
Bad csh gives:
"Within pairs of ''' or '"' characters, a newline preceded by a '\' gives a true newline character."
Maybe first describes only the case '\<newline>' 
and second is true for more complex: '......\<newline>....'
