Cshell within make

[michael b maxwell]

Thanks to all who pointed out to me that the reason "make" refused to
use cshell in script files it called is that the first line of the script file
should read:
#!/bin/csh
--I had used:
#/bin/csh    incorrect!!

Strange, I couldn't find this in the documentation I have, although I probably
didn't look far enough.  Indeed, the documentation seemed to imply that *any*
comment starting at the first character of a file would cause the script 
file to be run in csh, surely a strange practice...  And #/bin/csh worked 
everywhere that I tried it, until I tried make.  (Leaving it out would
result in the same file being run by sh.)  Why is make different?

A few observed that "make" should look at the SHELL variable.  It doesn't on 
our system (BSD 4.2), and a note today in news from Matthew P Wiener (of the 
Math Dept at UCB) says that the line in "make" that checks SHELL is usually 
commented out in the BSD version.  Anybody know why?
