I don't know what is causing this particular issue.

However, I have to strongly recommend that no one should use csh, in any
form, as the value for SHELL in a makefile.

There are too many odd things about the way csh works that makes it
inappropriate for use with make.  Primarily the issues involve quoting
and multi-line scripting, but there are more subtle issues as well: for
example the jobserver feature (not available on the Windows port--yet)
does not work with csh, because csh has an annoying habit of closing
open file descriptors when it starts up.


Really, csh is just broken--and for makefiles even moreso.

My HO, of course :-).
