System: NetBSD lola-granola 1.0-ALPHA NetBSD 1.0-ALPHA (LOLA) #36: Thu Jul 21 23:41:51 EDT 1994 jtkohl@lola-granola:/usr/src/sys/arch/i386/compile/LOLA i386

>Description:

/usr/bin/cpp uses unbound variable LIBS.  If your environment includes a
LIBS variable, it gets passed along in the invocation of
/usr/libexec/cpp.  This is Bad(tm).

It looks like $CSU has the same problem.

>How-To-Repeat:
  (setenv LIBS "xxx yyy zzz" && /usr/bin/cpp -C -DXXX /etc/motd)
