Problem buildling csh

[Adam Ciarciński <adam%NetBSD.org@localhost>]

Source from minutes ago gives:

src/bin/csh/file.c: In function 'pushback':
src/bin/csh/file.c:164:14: error: 'tp' undeclared (first use in this function)
src/bin/csh/file.c:164:14: note: each undeclared identifier is reported only 
once for each function it appears in
src/bin/csh/file.c:164:23: warning: unused variable 'svchars'
src/bin/csh/file.c:164:10: warning: unused variable 'buf'

Please, advice. :)

Kind regards,
Adam
